Error Close to Tolerance Limit
If a weighing error is close to but not greater than the tolerance limit, the
LR810 displays the following warning message.
The weight can be added as usual.
Trigger Fault
The optical trigger uses light beams to sense the position of the lifting arms.
The light beams are quite powerful and pass through normal build up of dirt
or dust. However, a large chunk of dirt or mud may block one of the beams.
If this occurs, the indicator displays the following message.
If this occurs, clean the faces inside the U shaped trigger sensor with a damp
cloth. There are two dark lenses on either side through which the light
beams pass. In most situations, the beams are never blocked. However, in
extremely dusty or damp environments, regular (say weekly) cleaning is
advisable.
Warning
Avoid using abrasive cleaners
