Simulated RTD temperature verification

Use the following to verify the performance of the Model DMM7510. Actual calibrator source values
will vary. RTD verification is based on the calibrator sourcing resistance and the Model DMM7510
conversion of the resistance measurement to calculated temperature based on the Callendar-Van
Dusen equation.
