8.3 Cable extensions
Extension cables must be shielded and of low capaci­
tance. We recommend the use of HBM cables, which
satisfy these requirements.
With cable extensions it is important to ensure that a
good connection is provided, with minimum contact re­
sistance and good insulation.
When using six‐wire circuitry, the effects of resistance
changes in the extension cable are compensated. If you
extend the cable using four‐wire circuitry, the sensitivity
deviation can be rectified by adjusting the amplifier. How­
ever, temperature effects are only be compensated when
operating with six‐wire circuitry.
Route the load‐cell connection cable so that any con­
densed water or dampness 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.
