OPERATIONAL GUIDE
INITIAL PREPARATION
Remove the battery cover on the rear of your
thermometer (see page 15).
Unwrap the battery. Connect the battery while
paying attention to the polarity and replace the
cover.
To switch on, press the ON/OFF
key on the front of the unit.
Your thermometer will carry out
a self-test. The LCD shows a
full set of figures during the self-test.
After the test, the thermometer will switch to the
measurement mode.
Plug a K-type thermocouple probe in and the
unit will display the temperature.
Note: In HI 9044, the probe is directly con-
nected.
If a probe is not plugged in, the
display will show "Er".
To switch your thermometer off, press the
ON/OFF key again.
MEASUREMENT RANGE
When switched on, the in-
strument defaults to the high
range with resolution of
1°C/1°F.
The measurement range may be changed to
a higher resolution range of 0.1°C or 0.2°F by
pressing the ON/OFF key again.
Note: Range switching causes all alarm
setting and memories to reset.
