Disconnect the 5-pin
connector (metal circular connector)
of the load cell cable from the scale.
Weight still fluctuates
/drifts / shows ERROR.
Check if the 5-pin female connector of the scale
has humid contacts. If so, use warm air to dry
off the connector (use for instance a hairdryer).
If after this operation the weight still fluctuates,
contact service.
