Detecting Insufficient Concrete Cover - Proceq Profometer 5+ Operating Instructions Manual

Tab. 5.1
• Select the small measuring range in the measuring
display. The large measuring range cannot be used
with welded reinforcing meshes.
Locating and measuring concrete covers
Here, the spacings between the bars of the other layers
of the mesh can also be located more easily. This par-
ticularly applies to the bars of the second layer.
The value displayed for the cover of a bar of the first
layer can vary by a few millimeters depending on wheth-
er the measurement is made over the point at which two
bars cross, or between the bars of the second layer.
If the rebars of the first layer are too close to
each other, it is likely to be impossible to loca-
te the bars of the second layer. See also
«Universal Probe», page 4.
Storing the measured values

values», page 11.

• Enter the bar diameter.
• Enter the limit value of the cover.
• Enter the bar spacing under the menu option «Neighb.
Bar Corr.» if the correction is required. The set limit va-
lue is not displayed in this case (see Fig. 5.1).
The setting of the audible locating aid is not of impor-
tance.
Measuring the concrete cover
With a preselected limit value, the probe can be moved
at a maximum search speed of 0.25 m/s without having
to watch the display. If the current cover displayed is less
than the limit value, an acoustic alarm sounds. When the
probe is over the bar, «—» is indicated in the «Current
concrete cover» display field.
Switching off the unit deletes the set limit
value.
