Temperature calibration
All the instruments of this series are pre-calibrated for a correct temperature reading. However, if there is a
difference between the measured and the real temperature (usually due to a probe malfunction), it is
possible to perform an offset adjustment of + 5°C.
After connecting the temperature probe in the correct measurement channel, use the keys
to correct the temperature offset value and confirm with
Restore Factory Default
If the instrument does not work properly or incorrect calibrations have been carried out, confirm Yes with
the button to take all the parameters of the pH menu back to the default settings.
IMPORTANT: the factory reset of the parameters does not delete the stored data.
