P2.9 Temperature calibration
All the instruments in this series are pre-calibrated for a correct temperature reading. However, if a
difference between the measured and the real one is evident (usually due to a probe malfunction), it is
possible to perform an offset adjustment of + 5°C.
Use the keys
and
to correct the temperature offset value and confirm with
.
