5.3 Determining the Bar Diameter
5.3.1 Rebars Connected with Binding Wires
A. Determining diameters without correction
For precise determination of the bar diameter, it is impor-
tant that there are no unnoticed influences that could fal-
sify the result. Therefore select a place on the structure
where there is sufficient spacing between the rebars.
If the spacings are too small, the resulting value will be
too high.
To measure the bar diameter in the first and second
layer, the minimum spacings a and b as shown in Tab.
5.2, page 13 are required.
• Select the «Measure w. Statistics» function.
• Carry out the RESET procedure. See also under
«RESET process», page 10.
• Place the probe parallel over the bar and press the
↑
key.
• The result of the bar diameter determination is
displayed in mm or inch.

Provided that the minimum spacings are observed, the
rebars can be measured with an accuracy shown in
