Select this option when the difference between Set Temperature and Cell Temperature is
less than 0.5 °C (in equilibrium).
Calibration:
Performs a multiple point adjustment, in steps of 5 °C, over the entire temperature range.
Select this option when the difference between Set Temperature and Cell Temperature is
0.5 °C or higher (in equilibrium). This temperature calibration takes approximately two hours!
This temperature calibration will adjust the internal thermistors to the certified thermistor in
the measuring cell over the whole temperature range.
