Operating Instructions

™

INSTRUMENT OPERATION - The

instrument is switched on by unfolding
the probe until the display shows the
temperature. The unit is turned off by folding
the probe back into the rubber probe retainer.
The probe should not be rotated more than
180 degrees as damage will occur. It is
recommended to store the probe, in the
closed position, when not in use.

Apply the tip of the probe to the substance, surface or area to be
measured. The probe should be allowed adequate time to stabilize to
the temperature of the item to be measured.

INSTRUMENT CLEANING - Clean the instrument regularly with
an anti-bacterial probe wipe to avoid potential food-borne bacteria
growth.

BATTERY REPLACEMENT - A battery symbol
indicates that the batteries will need replacing. The
instrument continues to measure accurately but
we recommend that the batteries be changed as
soon as possible. To replace the batteries, remove
