Rinse the probe with tap
water after every series of
measurements. If a more
thorough cleaning is required,
remove the PVC sleeve and
clean the probe with a cloth
or a nonabrasive detergent.
When reinserting the sleeve
onto the probe, be sure that
the sleeve is in the right
direction with the four holes
towards the cable end.
After cleaning the probe,
recalibrate the instrument.
The probe body is in PVC.
For this reason it must never
come into close contact with
a heat source. If the probe is
exposed to high temperatures
(above 50°C/122°F), the
rings might become loose
or detached, resulting in a
serious impairment of the
probe. In such cases, the
probe has to be replaced.
