Connection to the Load Cell
After proper grounding of the platform and the load cell, connect the shielded cable from the load cell to the
instrument ground. See
The load cell terminal board of the instrument may be connected to the 6-wire load cell; 4-wire load cell must
jumper sense to the excitation.
Sense is always enabled and must be jumpered to the same polarity excitation, when not using
6-wire load cell.
The sense compensates for drops in voltage in the part of the cable connecting the instrument to the load cell. This
is useful when the distance between the instrument and the load cell is greater than 32' (10 m). Normally this is
based on the load cell being used. When exceeding the length of the load cell cable, six wires must be used to
compensate for voltage drop. It is, however, recommended to use the cable supplied with the load cell and not to
modify it in any way.
