The PRM is designed to measure the peak value of high voltage D.C. pulse within its scale range, with a maximum capacity of 40 Kilovolts. Measurement can be made of peak values with rise time of less than one microsecond. The Model PRM Voltmeter is portable and is ideal for use in the field or laboratory. The Model PRM may also be used in design or production testing to measure ignition voltages, over-voltages caused by switching of electrical circuits and other voltages that often accompany high potential testing. Rugged construction assures dependability and virtually eliminates maintenance.

While the latest high voltage holiday detectors from Tinker & Rasor include an integrated volt meter, the PRM can be used to verify the units in the field. It is importatnt to note, however, that the PRM accuracy is ± 5%, while the integrated voltmeters of the Models APS and AP/W are ± 5%.
