Proceq Profometer 5+ Operating Instructions Manual page 17

Irrespective of the settings, the signal value is
a yardstick for the distance between the probe
and a metallic object.
• The bar direction can be detected by moving the probe
in the direction of its longitudinal axis along the rebar.
Make sure that the signal value and the current cover
remain as constant as possible.
Storing the measured values
To store the measured values, select an object number
in the menu.
• Press the PRINT/STORE key to store the measured
value shown in the field «Memo».
• Use the ↓ key to delete the measured value, or in the
case of several values, the last of the remaining mea-
sured values.
Warning!
You cannot undo the deletion of a value!
• To receive a statistical evaluation of the stored measu-
red values, press the END key.
• If you then enter a limit value («MENU» → «Limit Value»),
the percentage of the measured values which are
below the entered limit value is displayed.
• Pressing END again completes the measurement
series and starts a new one with an object number that
is incremented by 1.

Measuring the diameter
See «Rebars Connected with Binding Wires», page 13.
5.1.2 Welded Reinforcing Meshes
The unit cannot detect whether the rebars are welded to
one another or connected with binding wires. The two
reinforcement types with the same dimensions however
create different signals.
Settings
• Proceed as described under «Rebars Connected with
Binding Wires», page 13.
• Observe the following exception:
The setting of the bar diameter must be slightly higher
than the actual diameter (see Tab. 5.1, page 12). The
input depends on the bar diameter and on the mesh
width. With special constructions, this value should be
determined by means of a test on an open system.
Use different distance pieces to find out the diameter
setting at which the correct cover is indicated.
Examples for diameter settings:
