Perform these 5 steps to calibrate a PT100:

1. Place the reference probe and the UUTs in the temperature source in close proximity to one another.

2. Connect the leads to the readout(s) ensuring proper 2-, 3-, or 4-wire connection.

3. Measure the reference probe and determine the temperature.

4. Measure and record the resistance of the UUT(s).

5. Fit the data.
