Table calibrator source values based on NIST Monograph 175, reference data 60, version 2.0.
Use the following values to verify the performance of the Model DMM7510. Actual values depend on
published specifications (see
Example reading limit calculation
(on page 2-8)).

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.
