Voltage will be supplied by another I/O board. I want to vary the resistance to simulate the changing of the temperature with the digital potentiometer. Does this make sense? I would like to place the board that will be simulating the 10k ohm thermistor in the same location as the real 10k ohm thermistor.

I am trying to simulate earlier captured data.

I do not have a schematic for the sensor!

Thanks,
Scott
