• If more than one load cell is faulty, the faulty cells can be identified using
a multimeter on the scale unit weight-totalling board to check each cell in
turn, as follows:
- Remove the four screws on the scale unit cover.
- Check that the four load cell cables are connected to the scale unit.
- Measure the voltage at the connectors on the weight-totalling board,
between terminal 2 and 3 for each load cell. The normal value for an
unladen machine is approx. 3-5 mV (DC). A value different from this
indicates that the load cell is faulty.
