3.1
Organize Scans in Projects
3.1.1 Project List
In the upper part of the Project Management window (2), the project list of the current Archive (1) is displayed with additional information. The meaning of the last three columns is: number of Imagescans (# IS), number of Quickscans (# QS) and total number of scans (# Total). Click one of the column headings and the table will be sorted by this column; by clicking the column heading again, the sort sequence will be changed again. To access general project editing functions, open the pop-up menu by clicking with the right mouse button on the applicable project in the project list.
The Project Info (3) of the selected project is displayed between the Project List (2) and the Scan List (4). The scan list contains all scans belonging to the selected project. You can change the space distribution between project list and scan list by moving the bar (5) to the top or the bottom.
Thus the Project Info window described above will open containing a default value for the project name and blanks for the remaining zones. Complete these zones and click the OK button in order to create the project.
To delete a project (including all scans contained in it), first select this project from the project list and then press "Del" or select the function “Delete” in the Edit menu or the context menu. The project and the scans contained in it will only be deleted after you have been prompted for confirmation:
Or activate the setting “Show large preview images” in the View menu to set a second display mode of the scan list:
In both cases, the scan name can be directly edited. To do so, you will need to click the scan name of a selected scan once:
If you move the mouse cursor over a preview image, short information about the scan will be displayed.
In the scan list, select "Edit Comment..." from the pop-up menu (right mouse click) to add a comment to the scan and play the audio comment:
To open a scan for further analysis purposes, double-click an item in the scan list.
3.1.3 Moving/Copying Scans
To move a scan to another project, drag the scan in the scan list to the selected project by using the mouse. Keep the mouse button pressed as long as the cursor is placed over the project to which you want to move the scan:
If you keep the Ctrl button pressed during the described operation, the scan will be copied instead of being moved. In this case, a small “+”-symbol will appear in the mouse cursor:
The clipboard is another option for copying or moving scans. Thus, a scan is temporarily stored in the clipboard to be pasted later in any other project.
For the selected scan, use the “Copy” function button (“Cut” for moving the scan) either in the Edit menu or in the context menu (right mouse button) or by pressing the button combination Ctrl+C (Ctrl+X for moving):
Then select the destination project from the project list and use the “Paste” function button either in the edit menu or in the context menu (right mouse button) or by pressing the button combination Ctrl+V.
3.2
Selecting/Configuring a Connected Device
When a device (PSA 100 Monitor, PSA 97 USB flash drive) is connected to the computer's USB interface, an additional column will appear on the left side of the window. In this column, all projects (top) and scans (bottom) that are stored on the device will be displayed:
If more than one device is simultaneously connected to the computer, the device to be displayed can be selected from the Drop-Down-Box top left:
To create projects on a PSA 97 Data Stick or a PSA 95 Memory Card, this device must necessarily present a special data structure. Select the function “Prepare/Setup new device” in the Drop-Down-Box to create a new data structure.
3.3
Transferring Projects or Scans
3.3.1 Using the Buttons
Using the buttons (1) and (2) in the middle of the screen, projects (1) and scans (2) can be transferred from the device to the archive folder and vice versa. The data saved on the device will be preserved.
To transfer a project, including the scans contained in it, from the device to the archive folder, select a project from the project list of the device and click the “>” button between the project lists (copy single project). If a project having an identical name already exists in the archive folder, the scans of the project saved on the device will be copied to the correspondent project in the archive (scans that are already saved in the destination project will be
preserved). If scans with an identical name already exist in the project in the archive you will be notified accordingly and given the choice of overwriting the scans or cancelling the operation.
If all projects are to be transferred from the device to the archive folder, click the “>>” button between the project lists. Depending on the number of scans saved on the device, the copying operation will take some time.
To transfer one or all projects from the archive folder back to the device, use the “<” or “<<” buttons between the project lists.
To transfer a single scan from the device to the archive folder, first select a project on the device as well as a project in the archive folder, then select a scan from the scan list of the
device, use the “<” or “<<” button between the scan lists.
3.3.2 Using Drag&Drop
To transfer a project from the device to the archive folder, drag this project from the project list on the device in the project list in the archive folder by using the mouse (also possible the other way round).
To transfer one single scan using Drag&Drop, select a scan from the scan list on the device and use the mouse to drag it in the scan list in the archive folder. The scan may also be directly transferred to another project by dragging the scan in the project list in the archive folder.
3.4
Importing Projects/Scans
Projects or scans can be copied or moved from the Project Management module of the Hilti PROFIS PS 1000 application to any desired folder or drive of the PC. To do this, use only the methods described below from within Hilti PROFIS PS 1000. Do not use the Windows Explorer to move scan files. This will result in the files being write-protected.
If, during the Drag&Drop operation, objects are moved between different drives, these
objects will be copied, i.e. the object existing at the source location will not be deleted while a copy of the file will be created at the target location. If however objects are transferred within the same drive, these objects will be moved, i.e. with the Drag&Drop operation completed, this object will no longer exist at the source location.
During the dragging of an object, you can define what to do with this object: while the object is dragged, press also the “Shift” button to move an object, or Ctrl to copy it.
3.4.2 Using the Clipboard
Projects/scans can also be moved between the PC Software Hilti PROFIS PS 1000 and e.g. Windows Explorer.
Select a project or a scan in the PC software Hilti PROFIS PS 1000 and use the “Copy” or “Cut” function button in the Edit menu or in the context menu and press the button
combination Ctrl+C (copy) or Ctrl+X (cut). Paste the object from the clipboard at the destination location by using the Clipboard functions of e.g. Windows Explorer.
If archive folders have already been defined, you can select the current archive from the Drop-Down-Box top right:
Click the “Search folder” button to create a new archive or to activate an archive that does not show up in the list:
Select a directory and click OK to confirm.

4.1
Info Section
In 3D, this symbol indicates the starting point of a scan.
While the parameter “Concrete” is changed in the Analysis section “Param.”, the resulting indication of depth at the current position of the crosshair is shown in red in the Info section (1).
4.2
Function Buttons
The function buttons will guide you through the different process steps required for obtaining a correct and convincing analysis of the scan data. As determining optimal settings for displaying or processing the data frequently is an iterative procedure (see chapter 4.10, Instructions for Data Analysis), the process chain steps may directly be selected. Clicking one
of the function buttons will take you directly to the correspondent Analysis section, the clicked function button being shown in red.
Use this function button for switching between the visualization modes (2D/3D) and for indicating the view which is currently activated. In our example, the 2D display is activated. Another option for changing the visualization modes is to use either shortcuts (Ctrl+2 for 2D, Ctrl+3 for 3D) or the “2D” or “3D” functions in the View menu.
data. Changing one of these settings automatically triggers a reprocessing of the whole dataset, thus showing immediately the impact of the changed setting on the visualization of the measuring data, see chapter 4.3, Function button “Param.”.
This function button lets you select the settings which affect the visualization of data but not the processing, see chapter 4.4, Function button “Display”.
Choose this function button to set the visibility and coloration of various elements, see chapter 4.5, Function button “Config.”.
Choose this function button to generate a report or a preview image of a scan, see chapter 4.6, Function button “Extras”.
Choose this function button to place up to 8 drill-hole markers in the 2D display of a scan, see chapter 4.7, Function button “Drill-holes”.
Choose this function button to place up to 8 locally fixed annotations in a scan image, see chapter 4.8, Function button “Annotation”.
4.3
Function button "Param."
In this section, you can define the most important settings used in the processing of data, i.e. the numeric preparation of data. Each change made to this menu has great influence on the quality and accuracy of data. As soon as one of these settings is changed, reprocessing of the whole dataset is necessary, thus showing immediately the impact of the changed setting on the visualization of the measuring data.
"Lock Depth"
Clicking the option “Lock Depth” will fix all the parameters affecting the depth scaling (see chapter 4.3.2, Depth Scaling).
"Concrete"
The parameter “Concrete” adjusts the depth scaling. The material being scanned and its condition affect the depth indications for the object located. In order to obtain a correct indication of depth, the parameter “Concrete” must correspond to the physical
characteristics of the material scanned. The numerical value given here refers to the
characteristic known as “permittivity” in the field of physics (see chapter 4.10, Instructions for Data Analysis). If the set value is incorrect, a minor deviation from the true value will lead to the display of an incorrect object depth while in case of a major deviation from the true value, only incorrect objects or no objects at all will be displayed.
"Focus Offset"
The parameter “Focus Offset” lets you virtually shift the surface in order to improve the focusing of the data. We recommend only using this parameter if the default setting (“Focus Offset” value=1) does not provide a reasonable visualization of the data. In case of very heterogeneous materials or surfaces, “Focus Offset” may contribute to improve the data processing.
Typical value for parameter “Concrete” from to Concrete 5.0 8.0 Concrete wet 6.0 12.0 Concrete dense 6.0 9.0 Granite 5.0 8.0 Limestone 7.0 9.0 Sandstone 6.0 Asphalt 3.0 5.0
Value for the parameter “Concrete” correct
3. Taking the known depth of an object as a reference (see chapter 4.3.2, Depth Calibration).
4. Taking the known thickness of a slab as a reference: In a “raw” cross section image, the back surface of a slab is typically shown as an even line.
Provided the wall thickness is known, the parameter “Concrete” can be adjusted until the line described above coincide with the actual slab thickness.
4.3.2 Depth Calibration
As mentioned before, the depth scaling may be calibrated on the basis of the known depth of an object. Proceed as follows:
1. Position the cross hairs at the mid point of the object of known depth in the cross-sectional view. The mid point of the view of the object represents the upper surface of the real
object. The current depth value will be indicated in the Info section as black number. 2. Adjust the parameter “Concrete” using the cursor until the depth value shown in red (1) in the Info section corresponds to the actual depth value.
4.3.3 Section "Param."
The section “Param.” lets you define all basic settings of the process chain.
Changing a value in “Param.” will automatically start a reprocessing of the dataset.
"Filter Type"
To gain a clear view of objects in the near range, the data from consistent slices is filtered, thus masking reflections of the surface, slices and a possibly existing back surface of a slab. There is a choice of three options:
"Median": The standard option as it statistically represents the most robust method and
will in most cases ensure a satisfying visualization of the data. For each depth, the median value of the data will be subtracted.
"Selective": To calculate the data from consistent slices, this filter will identify areas in
the material scanned where no objects are located. In some configurations, e.g. in case of very narrow and compact grids this filter type will provide better results as the filter type “Median”.
"High-pass": This filter type will locally calculate the data from consistent slices for a
limited length of the recording. It is recommended choosing this option with long Quickscan recordings (QSR) where the material scanned varies over the scan length.
"Depth Range"
The “Depth range” parameter provides a choice of two settings, depending on the position of the object:
"Standard": Provides a good balance between clarity of the objects and a minimum of
interference.
"Deep": Makes objects at greater depth more easily visible but also increases the
interference seen in the image.
Background information: in a signal processing chain, this parameter corresponds to the choice of two different depth-dependent gain profiles (Gain). The setting “Deep” seeks to visualize as much objects as possible. It is recommended choosing this option if you want to visualize e.g. plastic pipes located next to steel reinforcement bars or objects located at great depths in an extremely dampening material.
approximately ±45°. This means that an antenna does not only capture the object located directly below the antenna but also objects located left and right to it. Due to this property of the antenna, the typical hyperbolas occur in the raw data. The position of an object is
represented through the apex of a scattering hyperbola. Like converging lens for
converging the light, an algorithm is used for synthetically focusing these hyperbolas. This method provides a more realistic and well-improved view of the data in the material. In case of the focus type “Fast”, the algorithm used belongs to the Stolt migration whereas the focus type “Extended” is an algorithm of the Kirchhoff migration.
"Data"
The parameter “Data” lets you select the data to display in the cross section image. You can choose between “Standard”, “Focused”, “Gained”, “Filtered” and “Raw”.
"1 Standard": This view shows the data as focused reflection intensities. Such a reflex
appears at the location of an object. The more an object is reflective, the higher is the shown intensity. With objects whose diameter is rather small compared to the wave length of the radar waves, particularly objects such as reinforcement bars or other long-shaped objects (e.g. cables or pipes), this method will provide a more realistic
visualization in two or three dimensions. The center of a reflection described above generally defines the object depth (see chapter 4.3.3.1, Technical Explanations for the Object Depth Determination). The display mode “1 Standard” is the last step of the whole process chain after focusing of the data and it represents the envelope of the focused data.
"2 Focused": When “Focus” is selected, all data originating from one object is brought
together. This approach is called synthetic focusing or migration. A scattering hyperbola seen in the raw data or the gained data is brought together to one single point. Thereby, objects close to each other can be better distinguished and objects at greater depths more easily recognized as the focusing centers the energy of the reflection on one point. Analysis of the sequence of amplitudes lets you distinguish between plastic pipes and reinforcement bars.
"3 Gained": The setting “3 Gained” compensates the dampening effect of the material.
The more the wave penetrates the ground the more it is dampened. This is the reason why objects at a great depth provide much weaker reflections then objects close to the surface. To gain a realistic view, it is necessary to compensate this difference in
reflection amplitudes. There is a choice of two algorithms which can be set by using the parameter “Depth Range”.
"4 Filtered": When “4 Filtered” is selected, the raw data is displayed after a filter that
subtracts the data from consistent slices has been used. This approach filters most of the reflections from the surface, the reflections from a consistent slice or the reflections from a back surface. Thus, smaller objects to detect can be made visible. To filter the data from consistent slices, different calculation modes can be used, see “Filter type”.
"5 Raw": When looking for special patterns such as in layers, it can be of advantage to
use the “Raw” setting. These are the actual raw data recorded by means of X-Scan PS 1000.
"Z-Summation"
Use the mouse pointer in the 2D display or the function Visualization Thickness to select the slice thickness of the depth section that will then be displayed in the screen as a top view. The setting "Z-Summation" lets you determine if the median or maximum value above this slice thickness will be displayed as a top view. Selecting the option “Median value” will generate a smoother view of the 2D top view than the option “Max”.
4.3.3.1 Technical Explanations for the Object Depth Determination
Determination of object depth for various object classes on the basis of the processed scan data and multiple reflections
surface.
If the diameter of a plastic pipe or conduit is <50 mm (2 in), the reflections from the top and bottom surfaces are superimposed. The reflections then cannot be isolated. In this case, the mid point of the reflection in the processed cross section image is positioned slightly below the top surface of the pipe.
Multiple reflections are normally observed when wide, strongly reflective objects (e.g.
metal plates) are scanned. These reflections are a result of the radar waves bouncing back and forward between the concrete surface or the antenna and the object. The interval between these multiple reflections is a multiple of the distance between the object and the surface (antenna). As a result of this characteristic, multiple reflections can be identified as such, and not as real objects (ghost objects).
After processing, the reflections from the edges of a plate are normally stronger than those from its center. This is due to the strong scattering hyperbola at an edge, which becomes focused at this point.

"Overlay"
To activate the “Overlay” function make sure that the checkbox is activated.
N.B.: If using an overlay, you can generally obtain better results if you use the focus type “Gained”.
"Thickness"
The “Thickness” value indicates the actual overlay thickness in [mm] (*). The display of the overlay thickness in the visualization is not to scale.
"Concrete"
The “Concrete” value indicates the relative permittivity of the overlay. Typical values of the parameter “Concrete” for the overlay are listed in the table below.
(*) NB: From a certain slice thickness depending on the value for “Concrete” of the material scanned and the overlay, focusing of the data through an overlay will no more provide reliable results, thus limiting the detection depth. In such a case, the general specifications are no longer valid.

The “Color Scheme” parameter lets you select a color scheme. There is a choice of nine color schemes. These allow you to change the appearance of the display or to adjust it to the prevailing lighting conditions, but have no other significance.
“Contrast”
Set a value between 1 and 100% to reduce or increase the contrast of the displayed image .
“3D Display Threshold”
The 3D view shows objects in the scanned material as isosurface. If the “3D Display Threshold” value is reduced, objects that provide only a very weak reflection, will also be displayed. In 2D, “3D Display Threshold” corresponds to the parameter “Contrast”.
"3D Transparency"
The 3D view also provides an image of cross sections. The “3D Transparency” setting lets you to vary the transparency of cross sections to make objects located behind another object visible.
"3D View"
The “3D View” defines the viewing angle from which to watch the data in 3D. It is possible to change the viewing angle at will by using the mouse to turn the 3D visualization. In addition, a presetting has been defined for every spatial direction.
“Object Smoothing”
If objects are aligned along one scan direction (x or y) and if these are longishobjects, activate the checkbox for smoothing the objects.
It is not recommended to activate this filter if the objects are inclined relatively to the coordinate axes and if the objects’ shape is very irregular.
For illustration purposes, you’ll find below a few examples how to work with cross sections.

advantage is that a selective analysis of certain areas in the depth of the scanned material can be carried out.
The cross section to the right of the top view shows the section at the current x-position of the crosshair.
Set the crosshair’s x- and y-position by left-clicking the mouse in the top view. Hold down the mouse button and move the mouse for browsing the different cross sections quickly.
Alternatively, you can set the position of the crosshair using the function button “Display” in the “Crosshair / Cross Section Image” section.
4.9.2.2 Displaying Unscanned Areas
Areas that are not taken into account in an Imagescan recording, will be shown through a continuous line which ends with an end mark on the upper side of the grid. In these areas, no information about the objects located in the material can be provided. Even if only one direction is scanned (e.g. only the direction) objects located along this axis (again the x-axis) cannot be indicated as only objects located transverse to the scan direction may be detected.

4.9.3.1 3D Stereoscopic View
To intensify the 3D deep effect, the PC software Hilti PROFIS PS 1000 lets you display a stereoscopic view after a color filter procedure has been applied. Pressing the button combination Alt+3 shows or hides the stereoscopic view. If the user uses red/blue glasses, his brain will produce a 3D visualization with deep. Use the function buttons “Turn” and “Zoom” to visualize this effect best as possible.
4.9.4 Quickscan Recording
Visualization of scan data of a Quickscan recording differs from a Imagescan recording as the data is displayed in only one direction, i.e. the scan direction, and scans may be up to 10 m (32.8 ft) long. Thus, a Quickscan recording will not show any cross sections transverse to the scan direction. Displaying the 10 m (32.8 ft) scan data requires a special manipulation during visualization. In the following chapter, these special steps will be separately described
4.9.4.1 2D Visualization of a Quickscan Recording
When recording a Quickscan image, the scan direction will be defined before recording starts. There is a choice of four scan directions which describe the orientation of the scan and facilitate allocation of the data to the measured object.
Scan direction Description Symbol
"from left to right" From the viewing position of the observer, the Quickscan image has been recorded from left to right. The length scale runs from left to right in ascending order.
"from right to left" From the viewing position of the observer, the Quickscan image has been recorded from right to left. The length scale runs from right to left in negative direction (ascending negative measurements).
"from top to bottom" From the viewing position of the observer, the Quickscan image has been recorded from top to bottom. The length scale runs from left to right in ascending order from top to bottom.
Below, you’ll find an example of each of these four scan options.
Scan direction: "from bottom to top"
4.9.4.2 3D Visualization of a Quickscan Recording
The 3D visualization of a Quickscan recording represents the total length of data. For efficiently processing a certain part within the display of the total length, manipulation of the 3D graphical image by means of shortcuts will be indispensable. The following manipulations are particularly useful:
Action Shortcut Description
Move Shift + left mouse button
The visualization image can be moved beyond the screen by holding and moving it with the cursor while
simultaneously holding down the left mouse button and the “Shift” button. This function may be of advantage if a certain
right mouse button + mouse up/down
or, in the main content, move the mouse forwards while holding down the right mouse button. To minimize the display, turn the scroll wheel backwards or, in the main content, move the mouse downwards while holding down the right mouse button.

Instructions for Data Analysis
The following instructions will take you stepwise through the example of a data analysis of an Imagescan recording.
4.10.1 Starting the PC Software Hilti PROFIS PS 1000
Step Instructions Screenshot
1 Start the PC software Hilti PROFIS PS 1000 by double-clicking the left mouse button on the desktop icon. Alternatively, use “Programs” HILTI PROFIS PS 1000 in the Windows Start Menu to start the program.
Double-click to open a scan in the scan list. The program will automatically download the dataset, process the data and then switch to the “Analysis” tab in order to visualize the data.
3 If you want to open a scan from another archive directory, drive or folder, use the menu bar under “File” “Open Scan File” and select the respective file using the File Browser.
4.10.3 Analysis and Visualization of Scan Data
If the visualization does not provide a satisfying result, proceed as follows:
Step Instructions Screenshot
6 In “Param.” “Data Processing” use the following standard settings:
7 In the section “Display” set the “Color scheme” to “Blue” and adjust the parameter “Contrast” to a value which enables a clearer visualization of the data.
9 Examine the two-dimensional top view in the main content. Hold down the left mouse button and move, on the lower cross section in x-direction, the cursor up and down to see objects in the slices of material scanned. Alternatively, use the parameter
“Display” “Cross sections” “z” to change the depth values by means of the cursor or by entering a numerical value. For the parameter “Thickness”, adjust the slice thickness by means of the cursor to better distinguish
10 After optimizing scan data
visualization and completing scan analysis, you may, if necessary, add drill-hole markers or “Annotations” to positions in the image and comment the scan.
11 Then switch to the 3D visualization by clicking the “2D/3D” function button.
13 The “3D Display Threshold” is set by the graphic renderer. To obtain an optimal view, you may possibly have to change this threshold again. Use the parameter
“Display” “3D Display Threshold” to move the cursor to the left or the right. Set the threshold value to the recommended value of 40 to 50%. Depending on the scan data, you can also use “Object Smoothing” to improve the image and to display the objects even more clearly as longish objects. Only objects whose echo signals are stronger than the "3D Display Threshold" will be displayed. Increasing the threshold will reduce the number of objects displayed. By reducing the threshold, objects reflecting weaker echo signals will also be displayed.

14 Optionally, you can insert a cross section in x-direction by activating the checkbox “x” in “Display” “3D-Cross section”.
16 Return to “Display” “Data Processing” and select for “Color Scheme” the value “Grey”.
17 Change the “Contrast” value until the raw data is clearly visible. You can change the position of the depth section in x-direction by modifying the y-position of the depth section in x-direction by means of the cursor “x”.
4.10.5 Generating a Report

the basis of a two-layer model using the option “Overlay” of the "Param." function. If the lateral variations of the material are too strong, we recommend to realize several individual Quickscan recordings and to process the data on the basis of the adjusted “Concrete” value. An overlay is used While an overlay has been used, it has not been
indicated during the scan data processing (option “Overlay” in the “Param.” function. Too many
objects are displayed (ghost objects,
overdetection)
Incorrect value for “Concrete”
Adjust the value “Concrete” until you obtain an optimal focusing of the data and the depth is correctly indicated (see chapter 4.3.1, Section “Depth Scaling”).
“3D Display
Threshold” in the 3D display too low
Adjust the value for “3D Display
Threshold” (Function button “Display”).
Depth range “Deep” When “Deep” in 4.3, Function button “Param.” “Depth Range” is selected, the data will be massively amplified. Thus, minor irregularities or border areas are possibly made extremely visible and displayed as real objects. Number of
displayed objects too low (underdetection)
Incorrect value for “Concrete"
Adjust the value for “Concrete” until you obtain an optimal focusing of the data and the depth is correctly indicated (see chapter 4.3.1, Section “Depth Scaling”).
“3D Display Threshold” in 3D display too high
Adjust the value for "3D Display
Threshold" (Function button “Display”). Depth range
“Standard”
Try the setting “Deep” in “Param.” “Depth Range”. Thus, the data from the depth will be massively amplified and objects reflecting weak echo signals are more likely to be displayed. From a certain Extremely absorbing Conductive materials dampen radar waves thus
PS 1000 does not display any objects, this does mean at all that no objects are located in the material scanned but that these objects cannot be detected by means of X-Scan PS 1000. Hint: if possible, scan both sides of the material to possibly detect objects from the back surface. Conductive films Conductive films are used in structures as vapor
barriers or reflectors. These films reflect the penetrating radar waves and prevent detection behind this film. In the raw data or a Quickscan view, this film appears as strong and continuous reflex.
Interspaces between objects too small
If interspaces between the objects are too small, any objects located below these objects are not visible (blocked view).
The back
surface or slices in the ground are not displayed
Filter type Unlike the process chain of X-Scan PS 1000 Quickscan, the process chain of Hilti PROFIS PS 1000 is designed to hide constant reflexes of the surface of layered structures or the back surface. The advantage is that smaller objects can be more easily visualized. Nevertheless, the disadvantage is that, with completion of the data processing, these constant reflexes will no longer be visible in the displayed data. To view it,
please select the value “Raw” in “Param.” for the displayed data.
Irregular display of Quickscan recordings of great length
Filter type In Quickscan recordings of great lengths, the material scanned will probably vary. In this case use the filter type “High-pass”.
Only objects in x-or-y-direction
Configuration In "Config." "Activate/Deactivate" you can use the checkboxes to select the scan direction to
Uneven or abrading material
Uneven or heavily polluted surfaces might be the reason for the travel sensors of X-Scan PS 1000 not being able to measure the distance actually covered. In this case, we recommend using an overlay.
Ghost objects in the border area
Edges and angles, transitions between different materials
Edges, angles and material transitions cause reflections which are visualized as objects. The PC software is designed to detect object in homogenous objects. If not possible, use the value “Deep” in “Param.” “Depth Range” which tries to minimize these transitions. Nothing to see in
the main content
Zoom and move It may happen that the 2D/ 3D data visualization in the main content is moved out of the visible area or that this area has been downsized by zooming it so that it is hardly visible. In the 3D view, click “Display” “3D View” and select “Diagonal front/left”. The visualization will be reset to the visible area and a reasonable zoom factor.
The archive folder in the Project Management section does not show any
projects
Invalid directory structure
If you transfer the data manually or by using the PSA 95 memory card to your PC, make sure to copy first a folder called "\Projects" as well as the data folder containing the projects in the
mentioned directory. For archiving the data, Hilti PROFIS PS 1000 requires to create the
following directory structure: ... \Projects\<Subfolder>\<Scanfiles>. The Project
Management does not show graphic preview images
Generating a preview image
In this case, the dataset has never before been processed or a preview image has never before been generated. Open the dataset, process the data using the appropriate parameters and generate a preview image using “Extras” “Preview image”.
