INITIAL PREPARATION
Remove the battery cover on the rear of your thermometer. Unwrap
the battery. Insert and connect it to the clip and replace the cover.
Connect the temperature probe to the probe socket on the top of the
meter.
To switch on, turn the rotary dial to the desired
resolutionin ºCorºF (dependingonthe model).
If a temperature probe is plugged in, the unit
will display the temperature.
With the rotary knob turned to the deci-
mal-point resolution (0.1ºC or 0.2ºF), "Er"
isdisplayed if the temperature reading falls
out of the instrument range (see Specifica-
tions on page 3-4). Turn the rotary knob
to the 1ºC or 1ºF position.
If "Er" is still displayed, check the probe cable
and connector.
To switch your thermometer off, turn the rotary
