CALIBRATION
All Hanna Instruments thermometers have been
accurately pre-calibrated at the factory.
It is generally recommended to have all ther-
mometers recalibrated at least once a year.
For an accurate annual recalibration, contact
your nearest Hanna Service Center.
Hanna Test Plugs provide a quick and easy
way to test the meter's accuracy by simply
connecting these Test Plugs to the probe
connector of the meter. If the reading differs
by more than 0.4°C (0.8°F) from the Test
Plug value, the unit is due for recalibration.
Choose the right Test Plug to suit your needs:

Your thermometer is factory programmed to
diagnose a fault or warn of low battery
levels. This is indicated by the error codes
on the LCD. Moreover, self-explanatory sym-
bols are used to remind the user of the
operating mode or conditions.
