OPERATIONAL GUIDE
INITIAL PREPARATION
Remove the battery cover on
the rear of your thermom-
eter, unwrap the battery and
connect it to the clip. Insert
the battery into the compart-
ment and replace the cover.
To switch on, press ON/OFF
on the front of the unit.
The thermometer performs a
self diagnostic test. The LCD
dispalys all the segments at
once, to ensure none are
missing.
After the test, the thermometer will switch to
the measurement mode.
If a temperature probe is plugged in, the
unit will display the temperature.
If the probe is not plugged
in, the display will show

To switch your thermometer off, press ON/
OFF again.
MEASURING SCALE (°C/°F) (HI 9057
only)
When the meter is turned on, it automati-
cally defaults to the °C scale. Measurements
can be performed on either the Centigrade
