6. PROBE CARE AND MAINTENANCE
For best results, always clean the temperature probe with clean tissue paper
after measurement to keep the probe in good working condition. Wash the
probe thoroughly with tap water if necessary to wash off any residue. Should
there be any thin oil film sticking on the probe, wash with mild detergent or soap
and warm water. Rinse probe thoroughly under running water. Blot it dry and
clean off with clean tissue.
To remove the probe, simply hold firmly onto the probe’s plastic holder and pull
the connector out of the meter’s socket. Store both the probe and meter into its
original packaging when not in use.
