2.2.7 Selecting the type of the sensor

The sensor type can be chosen in the TED8xxx modules by selecting the line
"Thermistor" respectively "AD590".

2.2.8 Calibrating a thermistor

2.2.8.1 Select the calculation method
If the relation between temperature and resistance for a given thermistor is known,
the PRO8 system is able to display temperature directly in °C instead of resistance in
Ω. Therefore, a calibration of the sensor in °C is necessary.
Two well known methods to calculate the resistance from temperature are
implemented:
•
The exponential method
•
The Steinhart-Hart method
In the channel menu you can choose between these two methods and enter the
corresponding parameters:
Select the line
Steinh.-Hart
resp.
Exponential
The right softkey toggles between the two methods.
