Fig. 2.4 Resolution
On concrete elements, measurements are often influen-
ced by neighboring bars. For parallel bars in the same
layer, the diagram in Fig. 2.4 shows the smallest bar
spacings a at which rebars are still identifiable individu-
ally in relation to concrete cover s. For intersection points
of the bar spacing a and concrete cover s above the cor-
responding curve the current value indicates the approxi-
mate depth of the reinforcement level. For possibility for
correction, see «Corrections», page 7.

For the SCANLOG model, the ScanCar is required to
perform the «CyberScan» and «Measure with Grid»
functions. For model S, it can be used as a carriage
without any other functions.
If the path measuring cable is connected, the
air gap of 4 mm between the probe and the
concrete surface is automatically corrected
when the concrete cover is displayed.
