OPERATIONAL GUIDE
Each meter is supplied complete with a 9V battery. Remove the battery cover
from the back of the thermometer, insert the battery and reattach the cover.
Connect the temperature probe to the probe socket on the top of the meter.
To switch the instrument on, turn the rotary switch to
°C or °F position (depending on model).
If a temperature probe is plugged in, the unit will display the measured
temperature.
After use, switch the 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 the nearest
HANNA Customer Service Center.
For a quick and easy check of the meter accuracy,
HANNA instruments
®
offers a series of CALIBRATION
TEST KEYS to be connected to the probe socket on
the thermometer.
If the reading differs more than ±0.4°C (±0.8°F) from the test key value, the
unit is due for recalibration.
