Value at analog input 1
The resolution is up to 0.0001 depending on the value.
Depending on the sensor and software averaging this
calculated value makes sense (Pt1000 is greater than Pt100
by 10).

Displaying the Temperature
The measured value per channel is displayed in degrees centigrads by default. The
command registers can be used to have the temperature value displayed in Fahrenheit or
the measured value in Ohms.
For converting temperatures the following formulas are used:
From Fahrenheit to degrees centigrades:
