PW10A... Single point load cells
2.1 Connecting in four-wire and six-wire configurations
When load cells calibrated in a six-wire configuration are connected to
amplifiers with a four-wire configuration, the sense leads of the load cells must
be connected to the corresponding excitation leads.
When connecting load cells calibrated in a four-wire configuration to amplifiers
in a six-wire configuration, a relevant bridge must be attached in the amplifier
input between the sense lead and the excitation lead.

2.2 Cable extensions
You must only use shielded, low-capacitance measurement cables to extend
the cables, making sure that there is a proper connection with minimal contact
resistance.
The cable of a six-wire load cell can be extended with a cable of the same type.
2.3 Shortening the cable
The cable of a load cell in a six-wire configuration can be shortened, without
this changing the calibration.
