8.8. Working with Waveform Library
8.8.1. Saving waveform to the Waveform Library To save waveform to the library:
Perform cable line test (see 8.5);
As a master channel select the channel with waveform you want to save (see 8.4.2);
press and in the pop-up window: "Save the waveform of channel x?" press button to confirm or “Esc” to cancel;
The device automatically opens the window "WAVEFORMS LIBRARY" (see 6.4.3);
Specify a name for the waveform (or leave the default name);
Finnaly, press the button ;
Close the window "WAVEFORMS LIBRARY" by pressing “Esc”.
ATTENTION. The device automatically saves the probing parameters used to get the waveform.
8.8.2. Loading waveform from the Waveform Library
The instrument lets you load and display up to three waveforms to a specialized memory channels (channels «MEM1» - «MEM3»). It is possible to simultaneously work with the data coming from the measuring inputs. To load the waveform from the library to the memory channel:
Open the window "WAVEFORMS LIBRARY"
Use and buttons to select the appropriate waveform from the library;
By pressing any of "F4" – "F6" load the waveform from the library to the display channel;
Close the window "WAVEFORMS LIBRARY" by pressing “Esc”
8.8.3. Delete waveform from the Waveform Library To delete waveform from the library:
Open the window "WAVEFORMS LIBRARY";
Use and buttons to select the appropriate waveform from the library;
Press "F9" opposite "Delete" selector;
In the pop-up window: "Delete the selected waveform from the memory?" - Confirm the action by pressing the button ;

Press "F5" opposite "Delete all" selector;
In the pop-up window: "Delete all waveforms from the memory?" - Confirm the action by pressing the button or press “Esc” to cancel;
To close window "WAVEFORMS LIBRARY" press “Esc”
8.8.5. Export waveform library to USB-Flash To export waveform library to the USB-Flash:
Open the window "MENU";
Insert USB-Flash into the USB-port;
Wait until the device identifies the USB-Flash (flashing USB-Flash LED);
Press "F1" opposite "Export waveforms library”;
At the end of the copying window pops up: "Waveforms library successfully exported to a folder (the path to the folder)" - confirm the action by pressing the button .
8.8.6. Import waveform library from USB-Flash
To import waveform library from USB-Flash into the device internal storage:
Open the window "MENU";
Insert USB-Flash into the USB-port;
Wait until the device identifies the USB-Flash (flashing USB-Flash LED);
Press "F2" opposite "Import waveforms library”;
Use and buttons to select the folder;
Press , a window pops up: "You're going to import the library to replace the current one.
Do you want to export the current library?" – Press button , to backup current library into an external drive before replacing. Press to proceed action without backup;
After copying window pops-up: " WAVEFORMS LIBRARY successfully imported" - confirm the action by pressing the button

8.8.7. «Screenshot» functionThe instrument provides the « Screenshot » function allowing to make a copy of the device screen in the "CHANNELS" and "PARAMETERS" windows. The picture is stored in non-volatile memory in JPG format with automatic naming by date and time. Screen shots are recorded to an external USB-drive with waveform files when calling the function "Export WAVEFORMS LIBRARY " (see 8.8.1.5).
To take a screenshot in one of the operating modes of "CHANNELS" or "PARAMETERS" press , in the pop-up window "Take a screen shot?" confirm it by pressing or cancel it by pressing .
