excitation voltage leads. However, there will be a voltage loss on the supply
leads due to the cable resistance that is still present and not compensated for
by the 6-wire configuration. A large part of this loss can be eliminated by a
calibration, however, the temperature-dependent part remains.

apply for the cable and transducer combination when connection is in a 4-wire
configuration, where the cable percentage must be added.
5.3

Shortening the cable

If the transducer is connected to an amplifier with a 6-wire configuration, the
transducer cable can be shortened as required without adversely affecting the
measurement accuracy.
5.4

Extension cables

Only use shielded, low-capacitance measurement cables for extension. Ensure
that the connection is perfect, with a low contact resistance.
The cable of a 6-wire transducer can be extended with a cable of the same
type.
5.5

Parallel connection

Only load cells with an aligned output (nominal (rated) sensitivity and output
resistance) are suitable for parallel connection. This option is not available with
type PW37 load cells.
