Cable extensions

Use only shielded, low-capacitance measurement cables to extend cables, making sure
there is a proper connection with minimal contact resistance.
The cable of a six-wire load cell can be extended using a cable of the same type.
The cable of a four-wire load cell should be extended with a 6-wire cable. At the
connecting point between the 4-wire and 6-wire cables, the supply leads must be
connected to the relevant sense lead.

Shortening the cable

The cable of a load cell with a six-wire configuration can be shortened without this
changing the calibration.
The cable of a load cell with a four-wire configuration should not be shortened, as the
particular cable length is taken into consideration in the calibration.
