The bar is positioned along the center line of the scanner and may be marked on the surface using a PUA 70 marking
pen. Depth measurement accuracy can be increased by entering the correct rebar diameter or by switching to accurate
depth measurement measuring mode (see 7.2.5.2).
7.2.5.2 Quickscan with accurate depth measurement
The measuring mode "Quickscan with accurate depth measurement" is selected by pressing the Confirm button.
The correct diameter must be known and previously entered.
The bar spacing distance must also be entered if within the 36 mm≦s≦120 mm (1.4"≦s≦4.7") range (see 4.3). This
value can be taken from building plans, confirmed by chipping away a channel in the concrete to view the bars, or
measured using Quickscan detection.
NOTE
A rebar spacing distance s≦36 mm (1.4") (see 4.3) cannot be measured.
The bar spacing distance can be calculated automatically using the Quickscan detection function by searching for
the center of the bar and pressing the red Record button when the scanner is over the mid point of the bar. Find the
mid point of the next bar and then press the Record button again. Bar spacing is then calculated automatically and
recorded.
