PT100 Resistance Simulation
Accurate simulation of low ohm values, such as P.R.T, can be performed by using the 1041
Resistance vs Temperature Relationship for Platinum Resistance Thermometer Detector Element (ITS-90)

Using this technique, the current passed through to resistor can be limited to a known value,
and lead resistance does not effect the accuracy of the readings.
