With cable extensions it is important to ensure a good connection with mini-
mum contact resistance and good insulation.
When using the six-wire circuit, the effects of resistance changes in the exten-
sion cable are compensated. If you extend the cable using the four-wire cir-
cuit, the sensitivity deviation can be eliminated by adjusting the amplifier.
However, temperature effects can only be compensated when operating with
the six-wire circuit.
Route the load cell connection cable so that any condensed water or damp-
ness forming on the cable can drip off. It must not be able to reach the load
cell. In addition ensure that no dampness can penetrate the open ends of the
cable.
