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.

Connecting principle for load cells with four-wire system

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.
