12. Calibration of temperature sensor
12.1 Useful information
The NTC temperature sensors used are very accurate and stable over time
All instruments are pre-calibrated and normally does not require any further adjustment even after
many years
However, in case of reading errors it is possible to make an adjustment of ± 5 °C
12.2 Calibration procedure
Connect the temperature sensor to the instrument, immerse the probe into a thermostatic bath
(pre-thermostated) together with the reference thermometer.
Wait 10 minutes for the stability, if the reading is equal to the reference sensor ± 0.5 °C then it is not
necessary to perform any calibration, otherwise access the parameter
P5.6
of setup menu.
Press the
key to enter the calibration, the display will show the temperature value measured at that
time.
Press the
and
buttons to adjust the temperature value, press the
button to confirm.
Press the
button to exit and return to measurement mode, the meter will save the adjustments
made.
To restore the values of temperature to the factory settings, access the parameter
P5.5
of setup menu,
select "
YES
" and press
