OPERATIONAL GUIDE
INITIAL PREPARATION
Each meter is supplied com-
plete with batteries.
Remove the back cover, un-
wrap the batteries and install
them while paying attention to
their polarity.
To switch on, press the ON/OFF key on the
front of the unit.
If the meter does not come on, make sure
that the batteries securely sit in their place.
Each time the thermometer is switched on, it
will carry a self-test to
ensure that no segment
is missing. The LCD
shows a full set of fig-
ures during the self-test.
After the test the ther-
mometer will resume its operational mode.
If a temperature probe is plugged in, the unit
displays the probe temperature.
If a probe is not plugged in, or the cable is
defective, the display will show "
