Note
Recalibration
9.3
Due to contamination (e.g. oil, water and particles) and component drift, an
annual recalibration of the sensor is recommended. Regular calibrations
are essential for cost transparency and correct billing.

Clean the sensor with approved cleaning agents only.
Do not use any chafing (abrasive) cleaning agents. These
can lead to irreparable damages to the sensor.
Carry out a new inspection after the cleaning, as required.
During cleaning, take care not to mechanically stress the
sensor plates, as they may break, causing irreparable
damage to the sensor. (Rinse the sensor, do not clean
mechanically.)
The sensor is to be cleaned in an ultrasound bath within
2 minutes. For example, a solution of 99% distilled water with
1% EM-404 from EMAG (aluminium and die-cast cleaner)
serves as a cleaning agent. Place the sensor in the mixed
solution – the sensor tip must be completely immersed. Switch
on the ultrasound unit for 2 minutes.
Rinse the sensor tip with pure distilled water and allow it to air
dry.
