You could build up a table of voltage versus temperature, knowing that the pullup voltage of our controller is a weak pullup through a 10k resistor with 3V excitation voltage. The voltage will be a simple resistor divider formula shown below. Create a spreadsheet with this formula and several representative values for R2 over the temperature range to calculate the associated voltage. Then fill in the results into a custom table. You can see more about custom tables here:
The easier method will be to send us the table of resistances & temperature and Chelsea will add it to the built in tables. While we’re at it I can update this example to show the voltages and custom analog range method above.
