Rinse the probe with
tap water after every
series of measure-
ments. If a more thor-
ough cleaning is re-
quired, remove the
PVC sleeve and
clean the probe with
a cloth or a nonabra-
sive detergent. When
reinserting the sleeve
onto the probe, be
sure that the sleeve
is in the right direc-
tion with the four
holes towards the
cable end.
After cleaning the
probe, re-calibrate
the instrument.
The probe body is in
PVC and for this rea-
son must never come
into close contact
with sources of heat.
If the probe is ex-
posed to high tem-
peratures, detach-
ment of the rings
might occur, resulting in a serious impairment of
probe function. In such cases, the probe has to
be replaced.
