Weighing equipment (Optional equipment)
• 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 for each load cell. The normal value for an
unladen machine is approx. -5 mV (DC). A value different from this
indicates that the load cell is faulty.
- Replace the faulty load cell(s) as described under “To replace a load
cell”.
