Section 3 Getting Started
Set the Scan Direction
You must tell the DCM the direction in which the crawler will be scanning. In some cases the crawler will be
moving in a positive direction along a scan while moving in reverse. This typically happens when scanning the
bottom course as shown above. In this case set the scan direction to Reverse (-). Otherwise, when you move the
crawler backwards the position will decrease. If you are moving the crawler forward and the scan direction is
positive, select Forward (+) otherwise, select Reverse (-).
Start Recording
When the crawler is positioned and all settings are correct, you are ready to record data. Click the Record button (or
press F9) and then move the crawler to the end point of your scan. The new locations should appear in the
Readings Grid on the right side of the window as you scan. The Position Indicator should move along the graph
showing the scanned area with a white background.
Saving / Discarding New Data
When the crawler reaches the end of the scan, click the Stop button (or press F10). The newly scanned locations
should now appear in a white background. At this point you can either save or discard the new data. If you want to
keep the data, click the Save Last button. If there are any locations in the area you scanned, they will be
overwritten. If there were problems such as loss of signal you will likely want to discard the data and scan the area
over. In these cases click the Discard Last button, you will be prompted to confirm it and the data will be removed
leaving any existing data in the scan.
Once you are finished scanning you can either save any changes to the data or discard them. To save them to a TK
file close the DCM by clicking on the Done button. You will be prompted for a folder and filename to save the data
to. If you do not want to save the changes made to the scan, click on the Cancel button and the DCM will close
without saving the data.
