7.1 Maintenance
Keep the weighing equipment clean. Accumulation of material between the fixed support frame
(static) and the live frame (dynamic) as well as around each load cell could affect the scale
accuracy.
Periodically check the alignment of the stringers and idlers in the weighing area.
When a problem arises in the conveyor, it is possible that the scale will be affected. Therefore,
periodic conveyor maintenance is important to proper scale operation which should include:
●
lubrication of all pulleys and idlers
● proper belt tracking and training
● proper belt cleaning and scraping
● proper take up operation
● proper material feeding and spillage control
You can observe the integrity of the load cells by performing zero and span calibrations. If the
zero and span deviations display a continuous unidirectional drift or the system cannot be
calibrated for any apparent mechanical reason, the load cells may be damaged.
