Load cells with four-wire system
Do not shorten or length connecting cables in the four-wire system, because the cable
resistance is temperature compensated. When the length of the connecting cable is altered,
the input and output resistances change. This change can be corrected by adjusting the
scale, but temperature-dependent resistance changes are not compensated for the missing
or additional length of cable.

Note
No calibration approval
In scales requiring official calibration, the connecting cables for load cells in a four
-wire
system must not be shortened or lengthened.
