There is a limit to the minimum spacing of bars depending on the cover
depth and rebar diameter. It is impossible to distinguish between indi-
vidual bars above these limits.

2.5 Sphere of influence by Ferromagnetic Material
MC (SLA)

Sphere of influence: Diameter 400 mm / 16 inch
Any ferromagnetic material within the
sphere may have an influence on the
signal value (e. g. during a reset)

NOTE! This effect can be reduced by the neighboring bar
corretion implemented in the Profometer PM-6.
3. Operation
3.1 Getting Started
Battery Installation
To install the Battery (B) into the Profometer Touchscreen Unit (A), lift the
stand as shown. Insert the battery and fasten in place with the screw.
Figure 5:
Insert Battery
There are two status LEDs
1
and above them a light sensor. The upper
LED is red while charging and turns to green when it is fully charged. The
other LED is application specific.
NOTE! Only use the power supply provided.
• A complete charge requires <9h (Instrument not operating)
• Charging time is much longer if the instrument is in use.
• An optional quick charger (Part No. 327 01 053) can be used to charge
a spare battery or to charge the battery outside of the instrument. In
this case it takes <5.5 h for a complete charge.
