eliminated by a calibration, however, the temperature‐dependent part remains.

apply for the cable and transducer combination when connection is with four‐
wire configuration, the cable percentage must be added.

6.3 Shortening the cable

As the transducer connection uses a six‐wire configuration, you can shorten
the 6‐wire transducer cable without affecting the measurement accuracy.

6.4 Cable extension

The cable of a six‐wire force transducer can be extended with a cable of the
same type.
Only use shielded, low‐capacitance measurement cables for extension. En­
sure that connection is perfect, with a low contact resistance.

6.5 EMC protection

Electrical and magnetic fields often induce interference voltages in the mea­
suring circuit. Therefore:
• Use shielded, low‐capacitance measurement cables only (HBM cables
fulfill both conditions)
• Do not route the measurement cables parallel to power lines and control
circuits. If this is not possible, protect the measurement cable with e. g. steel
conduit.
• Avoid stray fields from transformers, motors and contact switches.
• Do not ground the transducer, amplifier and indicator more than once.
• Connect all devices in the measurement chain to the same grounded
conductor.
