With regard to operation and user programming, special attention must be paid to the sections marked with the symbol.

The “Sartorius Win Scale” application is a type-approved driver program for a verifiable display and alibi memory used to store values measured by one or several balances, scales or weighing platforms (weighing modules). Communication between a PC and the balance, scale or weighing platform takes place over a serial RS-232/RS-485 data interface. The devices must be suitable, set up and certified for the transmission protocol xBPI (extended BBBBBalance PPPPProcessor IIIIInterface) or SBI (SSSSSartorius BBBBalanceB IIIIInterface), which are used for communica-tion. In the configuration of xBPI for some model series, it is possible to show the verified display and operating settings on the screen of the PC. No additional operating terminal for the weighing platform is then required.

In the configuration of SBI for other model series, the program is suitable for secure storage of the verified display values on the PC (alibi memory). The display and operating settings of the scale then continue to be used.

It is therefore possible, for example, to connect scales of the FB, FC, FD, LA and LP series, isi-industrial terminals and IS weighing platforms. If you use “Sartorius Win Scale” in conjunction with an IS weighing platform, an “isi” industrial display and operator terminal is not necessary. Several devices (up to 31) can be connected via a special network (“xBus network”) in which each device is identifi-able by a unique address.

The “Sartorius Win Scale” application is used:

– to emulate a verifiable display and

operator terminal (a “verifiable

window”) on the PC. The verifiable

window is placed on the screen in a

location selected freely by the user

and cannot be overwritten there by

any other application.

– for verifiable storage of data (in the

alibi memory; please see the section

entitled “Alibi Memory” above on the

right).

– as an interface between the user,

other software processes running in

parallel (DDE clients: D

D

Dynamic

ata

E

Exchange) and the scale or weighing

platform.

Example:

Data exchange between the scale or IS weighting platform and the PC takes place over a special, verifiable communi-cation library that is adapted to the external device. Data from the device is stored in alibi memory, which provides reliable protection against manipulation. The alibi memory enables the user to retrieve and further process verifiable data directly from the balance, scale or weighing platform using his own software. Furthermore, the user can take advantage of the range of commands available to him to initiate various functions on the balance, scale or IS platform (e.g. taring/ zeroing the display, starting calibration/ adjustment, accessing or changing the balance or scale operating menu). On verifiable devices, the range of commands is limited accordingly.

Alibi memory

The determination of the mass of an object for trade purposes is subject to calibration and verification requirements. If, for example, an invoice indicating the mass of an object is generated via a connected electronic data processing device (the number of intermediate stations does not matter here), calibration and verification regulations apply all the way to the printout of that invoice or any other record. The connected electronic data processing device can be a PC or computer network, for which it would be unrealistic to demand type approval certificates or verification.

However, in order to comply with the requirements of this legally regulated area, the concept of “alibi memory” was created. This is a type-approved, protected memory. Data to be further processed in transactions subject to calibration requirements is stored in this memory, where it cannot be manipulated. The data can be reaccessed on command at any time. When the data is processed, it is only necessary to indicate an ID that subsequently allows for unique retrieval of the stored data. It is the responsibility of the operator to ensure that this takes place. The archiving duration of the data is regulated at the national level. Compli-ance with the established periods is also the responsibility of the operator. Since this may become problematic for large amounts of data and long storage times, the Sartorius memory concept permits the stored data to be securely exported and reimported as required.

– “Sartorius Win Scale” can be used in legal metrology either as an addi-tional device or as a display and operating terminal (for balances and scales without an integrated display). In both cases, calibration by a duly authorized representative of Sartorius AG or calibration authorities is required. Subsequent installation of “Sartorius Win Scale” for use in conjunction with a balance or scale that has already been calibrated requires recalibration by the calibration authorities.

– The section entitled “Information in the Display” in the “Operation” section describes the inspection of the display required during calibration to ensure that the data is presented correctly. In addition, the mandatory inspection of correct storage of the weight values subject to calibration in the alibi memory is explained under “Function Test of the Alibi Memory” in the section entitled “Accessing the Service Menu” in the “Operation” section. The mandatory comparison of the software ID with a target value is described under “Reading Program Information” in the section entitled “Accessing the Service Menu” in the “Operation” section.

– When using the “Sartorius Win Scale” application, it is imperative that you follow the rules listed below: The display window of “Sartorius Win Scale” may not be imitated. This means that no similar display window can be generated, since this could lead to confusion with the display window of “Sartorius Win Scale.”

– The display window of “Sartorius Win Scale” in XBPi mode may not be hidden. The application has been designed so that the display window reappears in the foreground of the screen at least after any change in the readout from a connected weighing instrument. It is therefore up to the operator to ensure that no attempts are made to place the display window in the background, to hide parts of the window or to falsify the window with outside information.

- In SBI mode, no verifiable readout may be shown in the display window; for this reason, hiding of the window is permitted.

In addition to inspection of the findings with regard to the information displayed on the monitor (when using as a verifiable display), a function test is sufficient for the verifiable memory.

- The following function test of the verifiable memory is sufficient:

Performance of 5 weighings with saving of the data in each case (e.g. press the printout button on the scale). The weighing results should be recorded for subsequent checking. Inspection of the stored weighing results for agreement with the previously recorded values:

Click on “S” in monitor display to access the service menu. In the Password dialog, enter the user or system password and confirm with OK. In the Service Menu dialog, select “Verifiable Memory” and confirm with OK. In the Display Under Day File dialog, select the desired day and under Search enter the desired number under Verifiable ID, if necessary. The user must check the integrity of the legal metrology software modules every day. This is accomplished by accessing the software information (for this purpose, please refer to the sections entitled “Accessing the Service Menu” and “Reading Program Information” in the “Operation” section). A weight value may only be used and/or further processed in a verified context if it has been stored in the alibi memory.

– The storage time for legal metrology data depends on the application. It is the responsibility of the operator to ensure compliance.

– The operator is responsible for providing storage space for the alibi memory on the local hard drive. Configuration of the ring storage of the alibi memory must be performed by the operator (see here the section “Opera-tion” – “Configuring the Alibi Memory”). This also applies to measures for backing up the data.

– The alibi memory is protected against manipulation by checksums. Never-theless, the operator may not attempt to bypass this protection by analyzing or manipulating the files.

– The computer used must conform to EEC Council Directive 89/336/EEC and must bear the CE symbol. All connected peripheral devices subject to calibration requirements (keyboard, monitor, etc) must also bear this certification.

– The PC platform must fulfill the minimum requirements specified under “System Requirements” in the “Installation” section.

System Overview

Software System

The figure below shows the individual components of “Sartorius Win Scale” as a server in conjunction with a balance, scale or weighing platform and an external software application (client). Externally connected devices (balances, scales or weighing platforms) communicate with the help of modularly designed, device-specific drivers known as “verifi-able communication libraries.” Each library contains a defined range of functions (SARTOCOM protocol) as a software interface to a non-verifiable application and specific com-mands for communication with the external device. When the application is running, an appropriate verifiable communica-tion library is loaded for the particular external device with which the program is to communicate. All program-specific settings are stored in a configuration file. When the applica-tion is closed, a copy is made of this configuraapplica-tion file. If the original configuration file is destroyed, a valid configuration file can be restored from this copy.

xBus Network

All devices equipped with a serial RS-485 data interface and set to the xBPI communication mode can be linked together in an xBus network (see the figure on the left). In this special Sartorius network, up to 31 devices (balances, scales or IS weighing platforms) can be connected together. On scales or balances (such as the FB/FC or LA/LP series), the standard RS-232 data interface must be replaced with an RS-485 inter-face. This is available as an accessory for devices of the FB/FC series (YDO01F and YDO02F for scales and balances with high loads ≤12 kg) and for the LA/LP series upon request in the “Fast Factory” department.

To connect an xBus network or an individual device equipped with an RS-485 data interface (e.g. an IS weighing platform) to a PC equipped with a standard RS-232 interface, use one of the two options described below:

– Installation of an RS-485 interface card in the PC. For this purpose, Sartorius offers the W&T PC card 13601 (order no.: 62PC-Y014). This is a dual interface that can be installed in any commercially available PC with a standard AT bus. A detailed description is included with the card.

– Use of the 725319 interface converter (see figure on page 5). The RS-232 data interface on the converter is connected to the RS-232 interface on the PC via cable 7253143 (25-pin D-Sub female connector at both ends). The wiring diagram of

the RS-485 interface on the converter and all other details are included in the accompanying operating instructions. Because of the individual cable lengths used for data transmission according to the RS-485 standard, there is no standard cable for this purpose. If you operate IS weighing platforms in the xBus network, they must have their own power supply. If necessary, the IS weighing platform must be converted (exception: IS weighing platforms that are controlled by an isi industrial terminal and scales of the FD series). For information on connecting IS weighing platforms, consult the section “Connecting an IS Weighing Platform to the PC” under “Connecting Devices to the PC.” To ensure unique identification in the network, each component must have a unique bus address that is stored in the device. The addresses may have the values 1 to 31. The data exchange within the network takes place in binary. Cyclical data output from a device is not possible in bus operation mode. A detailed description of the xBus can be found in the “Protocol and Function Description of the xBPI Interface of the isi Operating Terminals.”

In addition to the EC type approval of the balance or scale, the associated test certificate with appendix must be presented for calibration. It must be determined whether the verifiable program is operating properly. The actual value of the software ID is calculated and displayed by loading the menu item “Information, Software” in the service menu. The saved set value (CB880838 for software version 1.0.... / 8228A94E for software version 2.0....) is also displayed. If both values match, the software has been loaded properly and the computer may be used for purposes subject to calibration require-ments.

The program and all additionally required files (e.g. initialization file, configuration file and help file) are delivered on a CD.

Installing Sartorius Win Scale Note:

Exit all Windows programs before installing the “Sartorius Win Scale” application.

The hard disk of the computer (i.e. the C:\ drive) must have sufficient storage capacity to accommodate the program (> 3.5 MB).

SBI

If weighing platforms are equipped with an RS-232 data interface, they can be addressed within the SBI protocol. In SBI mode, data can be received from up to three connected devices.

Note:

In legal metrology, only the connection of a single balance or scale is permitted in SBI mode! No multi-range scales or multi-division scales may be connected when using the SBI protocol. In addition to the EC type approval of the balance or scale, the associated test certificate with appendix must be presented for calibration. It must be determined whether the verifiable program is operating properly. The actual value of the software ID is calculated and displayed by loading the menu item “Information, Software” in the service menu. The saved set value (8228A94E version 2.0....for SBI) is also displayed.

If both values match, the software has been loaded properly and the computer may be used for purposes subject to calibration require-ments.

If the recorded data should be stored in the alibi memory, the configuration data must first be entered based on the information on the test certificate: in case of calibration, the calibration value “e” must be entered. Combined tare/null or blockprint setting, indication of d for scales d not equal to e.

For balances and scales with combined taring and zeroing function, “Combined tare/null” must be selected, for balances and scales with separate taring and zeroing functions, “Blockprint” must be selected. Serial number, decimal places, etc. are entered in the configuration dialog windows since this data is not automatically collected (as in XBPI mode).

Connecting Devices to the PC

Connecting the FB/FC series to the PC

Scales of the FB/FC series are equipped with a built-in RS-232 data interface. The data output port (12-pin, round socket) is connected to the PC via cable YCC01-03ISM5. If the PC has a 9-pin connector rather than a 25-9-pin connector, you must also connect a 6965619 adapter cable between the PC and the interface cable. Set the balance to operate in the “xBPI” commu-nication mode. For more information, refer to the installation and operating instructions for the particular balance.

Connecting the LA/LP series to the PC

Scales of the LA/LP series are equipped with a built-in RS-232 data interface. The data output port (25-pin D-Sub female) is connected to the PC via cable 7357312. If the PC has a 9-pin connector rather than a 25-pin connector, you must also connect a 6965619 adapter cable between the PC and the interface cable. Set the balance to operate in the “xBPI” communication mode. For more information, refer to the installation and operating instructions for the particular balance.

Connecting an isi Operating Terminal/FD Series to the PC The isi industrial terminal must be equipped with a serial RS-232 interface. Scales of the FD Series come standard with an RS-232 interface. The data output port (12-pin, round socket) is connected to the PC via cable YCC01-03ISM5. If the PC has a 9-pin connec-tor rather than a 25-pin connecconnec-tor, you must also connect a 6965619 adapter cable between the PC and the interface cable. Set the RS-232 interface (“COM” interface) to operate in the “XBPI-232” communication mode by accessing the system settings. For more information, refer to the installation and operating instructions for the isi industrial terminal or the FD series scale.

Connecting an IS Weighing Platform to the PC

IS weighing platforms are equipped at the factory with an RS-485 interface and, in general, do not have their own power supply. The weighing platforms are operated in conjunction with an isi industrial terminal, and power is supplied via the connecting cable. To directly connect a weighing platform (or several weighing platforms in an xBus network – see the section entitled “xBus Network” for more information) to the PC, the weighing platform must be retrofitted with its own power supply. For this purpose, you will need an “installation kit for an external power supply” (for line voltage or mains supply of 220V: order no. 6971889) and a YAS03IS upgrade kit.

To facilitate data exchange between the PC and the weighing platform, you must do one of the following:

– Use an RS-232/RS-485 interface converter, model 725219, which is connected to the PC via cable 7253143. The pin assignment for connecting a weighing platform is included in the installation and operating instructions for the interface converter.

– Install an RS-485 interface card in the PC. For example, the W&T PC card 13601 (order no. 62PC-Y014) is suitable for this purpose. Additional information on this can be found in the section “xBus Network” in the “System Overview” section.

– The connection between the device and the PC must be properly established (see also “Connecting a Device to the PC”). – The application must be installed

(see also “Installing Sartorius Win Scale”).

Double-click on the Win Scale icon on the PC desktop. > This starts the application.

An integrity test of the program file (“.exe file”) is performed first.

If this fails, a corresponding error message appears. The application is closed immediately. This implies that the program file has been manipulated. In this case, notify your Sartorius dealer, your nearest Sartorius Service Center or the International Technical Support Unit based in Goettingen, Germany, since you will not be able to run the program and it is, therefore, unusable.

If one of the error messages shown on the left is displayed when you start the application, “Sartorius Win Scale” will also close immediately.

In these cases, the application was not installed correctly or the file shown in the error message could not be found.

To correct this error: Reinstall the application (see the section entitled “Installing Sartorius Win Scale” for more information). If the error continues to occur, contact your Sartorius dealer, your nearest Sartorius Service Center or the International Technical Support Unit based in Goettingen, Germany.

If the self-test of the application is completed successfully, the verifiable window will appear on screen as the virtual display and operator terminal. The first time “Sartorius Win Scale” is run after reinstallation, the verifiable window is posi-tioned in the upper left-hand corner of the screen. Otherwise, the window remains in the position defined by the user the last time the application was accessed (see also the section entitled “Configuring the Display Position”).

The virtual display and operator terminal of the “Sartorius Win Scale” application is shown in a fixed area on the screen where it cannot be overwritten. It cannot be hidden by any other application, and it returns to the foreground of the display after each change to a measured value.

The figure on the left shows a practical example of the “Sartorius Win Scale” virtual display and operator terminal, which cannot be overwritten, together with another application (e.g. MS Excel).

If the application starts correctly but the communication library necessary for communication with the connected weighing instrument is missing, the error message “ERR APP 13” is displayed. The commu-nication library can be selected in the service menu (see the section entitled “Accessing the Service Menu” for more information). If the display window is empty, a weighing instrument was not selected. In this case, access the service menu, select the appropriate device and click on the on-screen button to confirm (see the section entitled “Accessing the Service Menu” for more information). If other error messages are displayed, consult the section entitled “Error Messages.”

You can access on-line help by pressing the [F1] key.

(22)

Defining the Communication Library

Purpose: Selecting the verifiable communication library necessary for communication with the connected weighing instrument (or instruments). In order to work with “Sartorius Win Scale,” at least one “verifiable communication library” must exist. This library functions as a driver for the connected weighing instrument and must, therefore, “correspond” to the device with which communication is to be established. The communication library (e.g. “srvind3301.dll”) is a separate file, not an integral component of the “Sartorius Win Scale” software module (see also “Software System” in the “System Overview” section), but it is included in the delivery. The supplied file enables communication with the most important Sartorius instruments via the xBPI protocol; please consult with your Sartorius dealer, the Sartorius Service Center or the International Technical Support Unit based in Goettingen, Germany, for special applications. For licensing reasons, an access code for each communication library is delivered separately; this code functions as a key to enable use of the corresponding library.

The following steps are necessary to define the communication library: – Selection of a protocol ID

– Assignment of the verifiable communication library linked to this protocol ID (entry of the file name with directory path)

– Entry of the corresponding access code – Updating of the library directory

Select the “System” user status by clicking on it.

Enter the system password and confirm by clicking on the “OK” button. > The service menu appears on screen.

Click on the “Communication library” button in the “Communication weighing platform” section of the menu or enter “[ALT] + L” on the keyboard.

(23)

> The “Communication Library – Settings” screen is displayed. Enter the desired protocol ID (e.g. “srvind3301.dll”). The protocol ID is user-definable and enables the application to use the communica-tion library linked to this name.

Enter the file name of the communication library with the complete directory path. To do this, click on “...” button, select the required file in the “Browse” screen, (e.g. “srvind3301.dll”) and confirm by clicking on the “Open” button. The file then appears in the “Commu-nication library” window.

Enter the access code. The access code is delivered separately with the product.

Update the communication library: Click on the “Update” button or enter “[ALT] + U” on the keyboard. If a communication library already exists, you will be asked to confirm that you wish to update the library.

> The selected communication library is displayed in the “Current configuration” box. If one or more libraries are already listed here, the new library will be placed at the top of the list.

To exit the screen and confirm changes to the settings: Click on the “OK” button.

To cancel without changing the settings: Click on the “Cancel” button.

Changing the current communication library (if several communica-tion libraries exist):

Select the new communication library in the “Current configuration” box by clicking on it with the mouse.

Update the communication library by clicking on the “Update” button.

Answer the prompt with “Yes.”

> The currently valid library (protocol ID, file name with directory path and access code) is redisplayed in the “Assign name” section. The list of available libraries in the “Current Configuration” box is reordered so that the current configuration is listed first.

(24)

Removing a Communication Library (If multiple communication libraries exist):

Select the communication library to be removed in the “Current Con-figuration” box by clicking on it with the mouse.

Click on the “Remove” button or enter “[ALT] + R” on the keyboard to remove the communication library.

> The currently valid library (protocol ID, file name with directory path and access code) is redisplayed in the “Assign name” section. The deleted communication library is removed from the list of all existing communi-cation libraries in the “Current configuration” box. If no communicommuni-cation libraries exist at this point, the error message “ERR APP 01” will appear in the virtual display and operator terminal. For the program to function properly, a communication library must first be defined again.

Configuring Communication with the Device

Purpose: Setting all parameters necessary for communication with a weighing instrument, such as the device ID, communication protocol, device address, COM port on the PC and other interface parameters. Proper communication with the weighing instrument can be tested. To establish communication between the “Sartorius Win Scale” applica-tion and an external device, the following settings are required for the application and the external device:

– The “Sartorius Win Scale” application must use the verifiable communi-cation library that corresponds to the external device. A name (protocol ID) that establishes the necessary connection is assigned to the library in the selection screen “Communication Library – Settings” (see also the section “Defining the Communication Library”).

– The device address, connection of the serial interface on the PC (COM port) and the interface parameters must be adapted for communication with the external device.

– The external device must be set to the transmission protocol configured in the “Sartorius Win Scale” application (see the section entitled “Connecting Devices to the PC”).

The external device must be correctly configured in order to select it for communication with “Sartorius Win Scale” via the button (22) in the virtual display and operator terminal. You can configure these settings in the “Weighing Platform – Settings” screen, which is explained below.

(25)

Use the mouse to click on the “S” (14) button or enter “S” on the keyboard. > A selection screen appears for entering the user status and corresponding

password.

Click on the “Weighing platform” button in the “Communication weighing platform” section of the menu or enter “[ALT] + W” on the keyboard. > The “Weighing Platform – Settings” screen is displayed (see figure on the

next page).

Enter the device ID in the “ID” field.

The device ID is user-definable. Once you have selected a device by clicking on the button (22) in the virtual display and operator terminal, this name appears in the field above the on-screen button (marked as (19) in the figure in the section entitled “Information in the Display”).

Note:

Each new entry in the “ID name” field opens a new set of parameters (= communication path). Several sets of parameters can exist for the same device. However, this makes little sense in actual use because all parameters (communication protocol and all interface parameters) must be identical for the same device.

Select the communication protocol for data transfer between the PC and the device in the “Protocol” field. Clicking on the button opens a selection window in which you can click on the desired protocol. This protocol name establishes the link to the verifiable communication library that supports communication with the external device (see the section entitled “Defining the Communication Library”).

Enter the device address in the “Address” field. The device address is a number between 1 and 31 (for an individual device, the address “0” is also acceptable) that is assigned only to that device. With the help of configura-tion programs, such as YAD01IS, a particular address can be assigned to a device. If you leave the “Address” field blank, the address will be interpreted as “0”.

Enter the number of the serial interface on the PC (COM port) used for data exchange between the PC and the device in the “COM Port” field. If, for example, the device is connected to the COM1 interface, enter “1” in the “COM Port” field.

Entry of other interface parameters, such as “baud rate,” “parity,” “hand-shake,” “data bits,” and “stop bits” is optional. If these fields are left blank, “kA” (no entry) appears in each field. If data is entered into these fields, however, it must agree with the configuration of the device interface. Otherwise, data cannot be transmitted properly between the PC and the external device.

To transfer the new communication parameters to the PC: Click on the “Update” button with the mouse or enter “[ALT] + U” on the keyboard. If you have changed an existing configuration (the entry in the “ID name” field was not changed), you must answer a prompt to confirm the updates. > The new set of parameters appears in the “Current configuration” list. This

list is arranged alphabetically according to the entries in the “ID name” field.

To exit the screen and confirm changes to the settings: Click on the “OK” button.

(26)

Changing a communication parameter set (if multiple parameter sets exist):

Select the set of parameters to be changed in the “Current configuration” box by clicking on it. The communication parameters that have been valid up to now are displayed in the corresponding fields and can be changed. If you change the data in the “ID name” field in the process, this will be interpreted by the program as a new set of parameters (see the note on the previous page).

Update the parameter set by clicking on the “Update” button.

> The changed parameter set is displayed again in the “Current configuration” list.

Removing a set of communication parameters (if several sets of parameters exist):

Select the set of parameters to be removed in the “Current configuration” box by clicking on it.

Click on the “Remove” button or enter “[ALT] + R” on the keyboard to remove the parameter set.

> The deleted set of parameters is removed from the list of all existing sets of communication parameters under “Current configuration.” If no sets of parameters exist at this point, the error message “ERR APP 01” will appear in the virtual display and operator terminal. This error message disappears as soon as proper communication to an external device is re-established.

Testing the connection to a device:

Select the connection to be tested by clicking on it in the “Current configuration” box.

> The corresponding communication parameters are displayed in the applicable fields.

Click on the “Test” button or enter “[ALT] + T” on the keyboard.

> The “Weighing Platform – Information” screen is displayed. If a connection to a particular device has been established, the applicable identifying data for that device, such as the model name, serial number and metrological data, appear on this screen. If the connection could not be established (e.g. due to faulty communication parameter settings), “???” appears in the “Model” and “Serial Number” fields.

To exit the screen: Click on the “OK” button.

Defining DDE Connection Parameters

Purpose: Selecting the communication parameters necessary for Dynamic Data Exchange (DDE) between a DDE server program and a DDE client program (see section “Communication with External Programs (DDE Clients)”).

As a DDE server program, the “Sartorius Win Scale” application can receive and execute queries and requests from an external program (DDE client program) (e.g. requests to read a net value at stability and provide this data to the client program or to tare the weighing instrument). The DDE server program makes information available for retrieval without actively seeking communication with other software processes.

DDE client programs can establish DDE communication with a server application using the DDE communication parameters made available by the server. These parameters are defined by the three terms “Service,” “Topic” and “Item”:

– The “Service” parameter is the name that the server program recognizes when a DDE client program attempts to establish a DDE connection.

– The “Topic” parameter describes the type of data source. – The “Item” parameter identifies the actual data requested by the

DDE client.

The entries for the DDE communication parameters are user-definable in the DDE server.

This section describes only the entry of connection parameters. For further information on the DDE interface and application exam-ples, refer to the section entitled “Communication with External Programs (DDE Clients).”

Enter the system password and confirm by clicking on the “OK” button.

Click on the “Connection parameters” button in the “Communica-tion DDE” sec“Communica-tion or enter “[ALT] + B” on the keyboard.

(27)

> The “Connection Parameters – Settings” screen is displayed.

Enter the “Service,” “Topic” and “Item” parameters in the respective fields. These must also be defined in the client application to be served by “Sartorius Win Scale.”

To confirm the settings: Click on the “OK” button.

If you do not want to save the settings: Click on the “Cancel” button.

Configuring the Alibi Memory

Purpose: Defining a directory path and storage period for data in the alibi memory.

Data stored in the alibi memory is protected against manipulation by a security mechanism (CRC: Cyclic Redundancy Check). The security mecha-nism is designed to satisfy the special statutory requirements that apply to the archiving of verifiable data. Data stored in this memory is considered verifiable for the entire period for which it is stored in the memory. The first time you run “Sartorius Win Scale” after installing the program, you must define a directory path under which files will be stored and protected in the alibi memory. The directory (“ESP” is generally selected as the name for the alibi memory) must be created on the local hard disk of the PC being used. It may not be located on a diskette or a network drive. Each time data is stored in the alibi memory, the program checks whether sufficient storage capacity exists under the defined directory path. As a ring buffer, the alibi memory is set up with a defined storage capacity allocated in days. Once the defined time period expires, the oldest day file is moved from the alibi memory to the archive directory “WINSCALE-ESP-DEL-FILES” (“archived day files”). The files moved in this way are protected against manipulation with checksums in the same manner as the files in the ring buffer. If an attempt is made to alter a file stored in the alibi memory or in the archive directory, the file is identified by the program as a manipulated file and removed from the alibi memory or archive directory. These files are stored in the directory “WINSCALE-ESP-CRC-ERROR”.

Use the mouse to click on the “S” (14) button or enter “S” on the keyboard. > A selection screen appears for entering the user status and corresponding

password.

Click on the “Settings” button in the “Verifiable Memory” (alibi memory) section of the menu or enter “[ALT] + E” on the keyboard.

(28)

> The “Settings” screen is displayed.

Enter the time period for data to be stored in the ring buffer (1 to 30,000 days) in the “Time frame” field. The time period is dependent on the legal requirements of your country.

Enter the path for the “Verifiable Memory” directory in the “Memory path” field. The default setting for the path is “C:\ESP”.

Note:

The alibi memory (ring buffer) must be located on the local hard disk. If this is not the case, a corresponding error message will be displayed, and you will be given the option of correcting the error (see

the figure below on the left). If you do not make a correction, the default “C:\ESP” will be used as the path.

Note:

The paths for archived data (“WINSCALE-ESP-DEL-FILES”) and altered data (“WINSCALE-ESP-CRC-ERROR”) are created as subdirectories of the alibi memory (ESP).

To save the configuration: Click on the “OK” button or enter “[ALT] + O” on the keyboard.

To cancel the configuration: Click on the “Cancel” button or enter “[ALT] + C” on the keyboard.

Function Test of the Alibi Memory

Purpose: Testing the alibi memory to ensure error-free function. Immediately after it has been configured, the alibi memory must be tested to ensure error-free function and compliance with the appli-cable legal requirements. This is done by performing several weighing operations, storing the resulting data in the alibi memory, accessing the stored data and checking to ensure that it was stored correctly (for more information, see also the sections entitled “Writing the Weight to Alibi Memory” and “Reading the Alibi Memory and Exporting Data”). Perform a weighing operation and store the weight in the alibi memory. To do this, click on the “E” button (15) with the mouse or enter “E” on the keyboard (see “Writing the Weight to the Alibi Memory”). Repeat the procedure several times with various weights.

To access the service menu and read the data in the Alibi memory (see also “Accessing the Service Menu” – “Reading the Alibi Memory and Exporting Data”):

Click on the “S” button (14) with the mouse or enter “S” on the keyboard.

> A selection screen appears for entering the user status and correspond-ing password.

Click on “User” to select this status. You can also select the “System” user status instead, which carries higher privileges.

Enter the password for the particular user status selected, and click on the “OK” button to confirm.

(29)

Select the alibi memory by clicking on the “Verifiable memory” button in the “Verifiable memory” section of the menu or by entering “[ALT] + V” on the keyboard.

> The “Display” screen appears.

To select a date: Clicking on the button opens a selection window in which you can click on the desired date.

Note:

If you do not first choose a date when selecting a data record, you will be alerted by a corresponding error message.

Select the desired data record by clicking on it with the mouse in the “Data record” box. As an alternative method, enter the verifiable ID for this data record. The ID appears in every data record as the first group of numbers before the date.

> The selected data record, which appears in compressed format in the “Data record” box, is shown in detail in the “Contents” section of the window.

Check the displayed data record to determine if it has a verifiable ID and a checksum. These must be displayed in their respectively designated fields. The checksum must be labeled with “OK:”. The actual checksum can be seen at the bottom of the data record display after the remarks, and the whole checksum can be viewed by sliding the scroll bar to the right side of the window (see figure).

(30)

Check the data records of all test weighing operations in the same manner. All data records must have a unique verifiable ID and a correct checksum.

If errors occur, notify your Sartorius dealer, the nearest Sartorius Service Center or the International Technical Support Unit based in Goettingen, Germany. In this case, the “Sartorius Win Scale” application may not be used in legal metrology.

Reading the Alibi Memory and Exporting Data

Purpose: Reading out data stored in the 3 memories for weights. The data records can be selected and exported for further processing. In the process, a copy of the current day file is created in ASCII format. The “Sartorius Win Scale” appl
