standards. The instrument indicates concrete cover
depth and distances in [mm] and [m] respectively.
US System of Units
In this system the bar sizes must be set in numbers 01
to 16. The «bar size #» specifies the diameter in eights
of an inch. In this mode the instrument indicates cover
depth and distances in inches and feet.
Example: Bar size #5 corresponds to a diameter of 5/8"
(15.9mm).
• To switch from mm to inches press the MENU key and
subsequently select «Basic Setups» and «Unit»

Object Number

The measured values can be stored under object numbers.
The following number is set automatically as the first
digit of the six-figure object number according to the
measuring function:
- 1 for «Measure w. Statistics»
- 2 for «Scanning Bars»
- 3 for «Measure with Grid»

Corrections

Neighboring bar corrections
This mode is mainly used for determination of the bar
diameter in close spaced parallel bar arrangements.
There are structures where the bar spacing is smaller
than indicated in Tab. 5.2. When measuring these bars,
the displayed value of the concrete cover is too low and
the diameter value too high. In such instances, correc-
tions can be made. This however only applies to the
parallel bars on both sides. The bars that are arranged
crosswise must have the minimum spacing shown in
Tab. 5.2.
• Enter the previously determined bar spacing. See
«Measure with Statistics», page 9, «Detecting Insufficient
Concrete Cover», page 12, «B. Determining diameters
with correction», page 14, «Making Reinforcement
Visible with CyberScan», page 14 and «Measure with
Grid», page 17.
2-Layer-Correction
This mode is used for cover measurement in congested
standard orthogonal bar arrangements. A more accurate
cover reading can be reached by use of this correction.
The congested bars induce a too strong measuring
signal which can be corrected this way.
• Select the spacings a and b which you determined by
locating the bars. In some cases the bar diameters
cannot be measured by the PROFOMETER 5+ and
must be determined by removing the concrete. The
diameter setting is automatically selected as 16mm.
