For setting via the PC select the PC radio button and enter the set point value into the edit box directly
following the radio button.
7.3.2
Pot Range
This sets the temperature range that the pot gives values for.
7.3.3
Pot Offset
This sets the minimum temperature point on the pot.
7.3.4
PC Set Point
This allows the set point to be fixed via the GUI
7.3.5
Control
The control radio button if checked inhibits the temperature control.
7.3.6
Output
The output edit box allows the a fixed output to be set. To use this the control should be disabled otherwise
any setting made will be over ridden by the control. Range 0 to +/- 1000

Sensor
7.4.1
Type
The supported sensor types are selectable from the list box; refer to the specification
section 7.6
in this
manual for supported temperature sensors.
7.4.2
X2, X, C Coefficients
These are quadratic coefficients than can be input to convert the sensor voltage measured into a
temperature. This can be used for other sensors so that these can calibrated.
Where temperature = (v * v * X2 ) + (v * X) + C
v is measured sensor voltage and temperature is calculated temperature
The C term allows the user to adjust / shift the temperature to compensate for variations in sensor accuracy.
It can be seen that this value simply added to the temperature value. So if your sensor was 1 degree out
then make C = 1.
Also provided is buttons to decrease / increase this value in 1 degree steps.
For NTC thermistors different parameters are required
