7.2.5 Quickscan
CAUTION
The scanner detects only reinforcing bars that lie at right angles to the direction of travel. Bars that lie parallel to the
en
direction of travel will not be detected.
Make sure that the object is scanned in both the horizontal and vertical directions.
An incorrect depth may be calculated for bars that lie diagonal to the direction of travel.
Quickscan can be used to quickly detect the positions and approximate depths of reinforcing bars, which can then be
marked on the surface. This is procedure is named Quickscan detection.
Another function in Quickscan mode is accurate depth measurement, which requires that values for bar diameter and
bar spacing are previously entered.
Alternatively, the data can be recorded and evaluated on the monitor or using the PC application. The average depth
of cover over the reinforcement over large stretches of the surface can thus be easily determined. This procedure is
known as Quickscan recording.
Switch on the scanner. The Quickscan symbol is selected first automatically.
Use the Confirm button to select the Quickscan function from the main menu.
7.2.5.1 Quickscan detection
Move the scanner over the surface. Reinforcing bars that lie at right angles to the direction of travel will be detected.
The distance covered by the scanner is recorded.
Signal strength indicated by the column in the display increases as the scanner approaches a bar and the depth value
is also shown. When the scanner is positioned over the center of a reinforcing bar:
The red LED lights.
A signal tone is emitted.
Maximum signal strength is indicated.
The approximate depth of the bar is indicated (lowest depth value indicated = center of the bar).
