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.
