To display a rebar as a
circle zoom the horizontal
and vertical axis to the
same scale.
The spacings of the rebars
are shown in blue.
The distances from the
start line to the first rebar
and from the end line to
the last rebar are shown in
white color. If the figures
are not shown, zoom in.

• To change a diameter tap on the rebar.
A window opens.
• Tap on the window and change diameter.
To erase set diameter to zero.
The new diameter is set and shown in orange.
The cover changes accordingly but the cover
curve remains except above the rebar axis.

In the Single-Line Mode one can also change from cover curve to signal
strength curve or no curve (see also “3.6 Review of Data”).
The path length measurement accuracy depends on the test surface. The
accuracy of measurements done on a smooth concrete surface (concrete
poured in metallic shuttering) is shown in the specifications, see “6. Tech-
nical Specifications”. On rougher surfaces the measured length may be
reduced or checked at certain intervals by setting markings on the test
surface and comparing with marks set on the display (long push on
12
).
After storage (tap
7
), the data can be seen in the Statistics View, the
Single-Line View and also in the Snapshot View if at least one diameter
was measured (see “3.6 Review of Data”).

NOTE! It is advisable to locate the first and second layer re-
bars with the Locating Mode to find the optimum line posi-
tion prior to measuring in the Multi-Line Mode.
The Multi-Line Mode is often used if cover, rebar location and rebar di-
ameters of mainly rectangular areas of different sizes must be shown (see
“3.6 Review of Data”), thus mainly for the first layer rebars.
In one measuring sequence a maximum of 62 lines can be scanned and
stored in one file.
• Enter the settings menu by tapping
5
.
• Set the correct settings as for the Single-Line Mode. Additionally set
the Line Height. If desired, set also “Align Rebar Position” and “Return
to start on new line”.
NOTE! “Align Rebar Position” should only be set, if all rebars
are running parallel to the start line (Y-axis).
