Making Reinforcement Visible With Cyberscan - Proceq Profometer 5+ Operating Instructions Manual

The result of diameter determination cannot be
stored.
B. Determining diameters with correction
There are structures where the rebar spacing is smaller
than indicated in Tab. 5.2. Corrections are possible for
these structures. However, this only applies to the paral-
lel bars on both sides. The bars that run crosswise must
have the minimum spacings shown in Tab. 5.2.
Procedure:
• Locate the parallel rebars carefully and mark them on
the surface of the concrete.
• Measure the rebar spacings using a measuring rod
and enter the data in the «Corrections» → «Neighb.
Bar Corr.»
• Select the «Measure w. Statistics» function.
• Hold the probe in the air and carry out the «RESET
process» as described on page 10.
• Place the probe parallel over a bar and press the ↑ key.
As bar diameter (d=...), the display shows the value cor-
rected by the influence of the neighboring bars.
• In addition to the bar spacing, the measured bar dia-
meter can now be entered in the menu.
With these settings, the concrete cover of those rebars
found to be situated close to one another can be deter-
mined precisely.
14 Measuring Process
Only concrete covers can be stored under the
selected object number, not the measured bar
diameter!
5.3.2 Welded Reinforcing Meshes
If diameters are determined on welded rebar systems,
results are displayed most of the time. These values are,
however, always too high and cannot be used.
5.4 Making Reinforcement Visible with
CyberScan
Model SCANLOG only (with mobile probe)
The rebars arranged below a defined measuring area
are displayed. Using the x/y scales, rebars which have
to be exposed, or points where holes have to be drilled,
can be transferred immediately from the display to the
measuring area and marked.
The measuring area must be scanned with the mobile
probe once in direction x and once in direction y (see
«ScanCar», page 5). The rebars are located and dis-
played extended to the full size of the measuring area.
Measuring areas of 0.5 x 0.5 m, 1 x 1 m or 2 x 2 m can
be selected.
If the area that must be measured is smaller than the
size of the selected area the bars are only shown in the
length they were measured.
