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 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.

Option: 6-wire cable connection (a choice of lengths: 0.35, 1.5 m; 3 m; 6 m)

2.2 Shortening the cable

When the 6−wire configuration is used, the load cell's 6−wire cable can be cut
off without impairing measurement accuracy.
The cable of a load cell in a four-wire configuration should not be shortened,
as the particular cable length is taken into account in the calibration.
