If the spacing distance is known, the value can also be entered manually using the Arrow buttons.
After setting the bar diameter and the spacing distance, the procedure is exactly the same as for Quickscan detection
( see 7.2.5.1).
7.2.5.3 Quickscan recording
WARNING
Always make an Imagescan or use Quickscan detection in both directions prior to making a Quickscan recording in
order to:
– establish the direction of the uppermost layer of reinforcement,
– minimize the risk of scanning a spliced bar,
– and immediately see if there are any ferrous materials in the concrete that may affect the accuracy of the scan.
CAUTION
Do not press the Record button before placing the scanner at the point where the scan should begin.
The scan should not, under any circumstances, be started or stopped while the scanner is directly over a bar. Keep
an eye on the display (observe a distance of at least 30 mm to the nearest reinforcing bar).
Incorrect or misleading measurements may otherwise result.
WARNING
Do not lift the scanner from the surface before stopping the recording or setting a marker.
To record the position and depth of all reinforcing bars detected, place the scanner on the surface and use Quickscan
detection to find a position where there are no bars present. Mark the starting point with a PUA 70 marking pen and
press the Record button. The diskette symbol appears on the screen, indicating that the scanner is recording data.
Move the scanner over the surface.
At the end of the scan, take care to ensure that the end point is not directly over a rebar. To stop recording, press
Record again. Use a PUA 70 marking pen to mark the end of the stretch that has been scanned.
NOTE
Reinforcing bars that lie at right angles to the direction of travel will be detected and automatically recorded. Check to
ensure that the settings are correct before beginning recording.
