Inspection of the sensor

6.1.1 Visual inspection

To check your sensor, we recommend the following
procedure:
1. The contacts of the connector must be dry. Mois-
ture, corrosion and dirt in the connector can lead
to false readings.
2. Check the cable for buckling, brittle areas or ruptures.
3. Before calibration always examine the membrane
foil optically for signs of damage. The foil must be
intact and clean. Dirty membranes should be wiped
clean using a soft, moist tissue.
h
Note: An undulated membrane has no influence on
the sensor performance, assuming the membrane
is intact.
4. The membrane body must be replaced if the sen-
sor has too long a response time, the reading is
unstable or subject to drift, and if the sensor can-
not be calibrated or the membrane shows sign of
mechanical damage.
5. Check the cathode area for discoloration, contami-
nation or cracks in the glass. If necessary rinse with
demineralized water and clean with a clean soft
brush or soft paper tissue.
a
Attention! Do not use any cleaning agents contain-
ing alcohol. This could damage the sensor or lead
to fault current.
a
Attention! The glass body is fragile and sensitive to
vibration.
