BN100A
The contact allocation of the socket Bu1 corresponds to
the standard of HBM transducers. In order to calibrate
with the six‐wire circuit the bridge excitation voltage con­
tacts of the BN100A are already bridged with the sensor
circuits G and F. Due to the fact that the DMP40 or the
DMP41 resp. regulates the excitation voltage, the cable
and contact resistances will have no influence on the cal­
ibration.
Calibration in six‐wire circuit is, however, only sensible if
the measurements are made also in the six‐wire circuit.
The PE connection on the rear enables additional metal
parts (e.g. metal table) to be integrated in the protection
concept.
