OPERATIONAL GUIDE
INITIAL PREPARATION
Remove the battery cover from the back of your thermometer.
Unwrap the battery and connect it to the clips. Insert the battery
and replace the cover.
Connect the temperature probe to the probe socket on the top of the
meter.
To switch on, turn the rotary switch to °C or °F (depending on
model).
If a temperature probe is plugged in, the unit will display the
temperature.
After use, switch your thermometer off by turning the rotary switch to
OFF.
CALIBRATION
All Hanna Instruments thermometers have been accurately pre-
calibrated at the factory.
It is generally recommended to have all thermometers recalibrated at
least once a year.
For an accurate annual recalibration, contact your nearest Hanna
Customer Service Center.
Hanna Test Plugs provide a quick and easy way to test the accuracy
of the meter by simply connecting these Test Plugs to the probe
connector on the instrument.
If the reading differs by more than ±0.4°C (±0.8°F) from the Test
Plug value, the unit is due for recalibration.
