Required equipment
Following instruments are required for calibration:
* 81/2 digit multimeter type Fluke 8508A similar with 0.
Configuration the calibrator
Calibrator should tested directly from the front panel terminals. Calibrator have temperature stabilize condition
at minimum hours before performance verification test started.
* High voltage source Heinzinger PNC-10000 similar with output voltage accuracy 0.
