If the data logger is used in severely contaminated media, the pressure sensor
must be checked for contamination from time to time, and must be cleaned as
necessary. Never use sharp-edged tools such as screwdrivers, and never apply
pressure at any point on the diaphragm.
Cleaning the level sensor
The protective cap over the pressure sensor on the level sensor can be removed
by hand. Then rinse the sensor in flowing lukewarm water.
The pressure sensor diaphragm is very sensitive.
Do not touch the diaphragm!
Cleaning the air pressure sensor (-AA versions)
To clean the pressure sensor as thoroughly as possible, remove the knurled nut,
battery sleeve and the protective sleeve of the sensor, and then re-install the bat-
tery sleeve, the protective cap for the interface plug and the knurled nut (without
the protective sleeve for the sensor) so that the electronics are protected against
water and moisture.
Rinse the sensor with clean lukewarm water. After cleaning and before fitting the
sleeves, make sure that all parts are dry.
The pressure sensor diaphragm is very sensitive.
