The PRT option simplifies calibration of high-accuracy resistance thermometers. Reliable readings are guaranteed regardless of measurement technique, because the calibrator uses passive precision resistors.When the PRT option is calibrated, the precise temperature values on the ITS-90 scale for PT-385 resistors are stored in the memory. The values can be recalled and displayed every time a specific resistor is chosen, to allow accurate calibration.
When combined with the SIMRC option, an additional 2-Wire variable output is available, which enables simulation of any value.
