5.1 Maintenance
In principal, the device is maintenance free. If necessary, clean the device housing when
switched off using a damp cloth and a non-aggressive cleaning solution.
Depending on the product, deposits or contamination can still occur on the diaphragm. If the
product has a known affinity, the operator must determine the cleaning intervals accordingly.
Once the device has been properly taken out of commission, the diaphragm can generally be
carefully cleaned using a non-aggressive cleaning solution and a soft brush or sponge. If the
diaphragm is calcified, decalcification by the manufacturer is recommended.
5.2 Recalibration
During the life cycle of the device, the offset or full-scale of the device may shift. If this occurs,
note that the signal value output will deviate based on the set start or end value of the measuring
range. If one of these phenomena does occur following prolonged use, recalibration is
recommended to ensure continued high accuracy.
INFORMATION!
Improper cleaning can result in irreparable damage to the measuring cell. For this reason,
never use sharp objects or compressed air to clean the diaphragm.
