MODEL PRM PEAK READING VOLTMETER
Use with Tinker & Rasor Models High Voltage Holiday Detectors
IMPORTANT NOTE: Do not use this instrument in an explosive environment.
UPDATE INFORMATION: The Model PRM has been updated for better performance when
used with T&R Models APS and AP/W with integrated voltmeter LCD displays, starting with
serial number 1177. Previously built units may be sent to the factory for update evaluation.
1.
The Tinker & Rasor Model PRM Peak Reading Voltmeter is designed to measure the
peak value
of
high voltage pulses within its scale range, with a maximum capacity of 40 kilovolts. Voltage
measurements can be made of peak values with a rise time of less than one millionth of a second.
2.
The Tinker & Rasor Model PRM Peak Reading Voltmeter consist of:
1 - Voltmeter
1 - Ground Cable
1 - High Voltage Cable with Red Clamp
3.
Unpacking
Check all components against the packing list. If damage has occurred in shipment, file a claim with
the carrier immediately. If it is necessary to contact your supplier or the manufacturer concerning
damaged or missing items, be sure to include all the information such as serial number, purchase
order number and invoice number. This will ensure you of obtaining proper and expeditious service.

Description
The Model PRM is a portable, battery powered, voltmeter capable of accurately measuring pulse type
high voltages such as those generated by the “so called” spark type Holiday Detector and clearly
recognizing the values of either polarity.
Equipped with large five-digit liquid crystal display and single control switch for selecting proper polarity
and testing of self-contained power supply.
The cables supplied with the meter are well insulated for the proper use in measuring high voltages,
however, care should be exercised not to physically hold or touch these cables or connections while
the high voltage potential is present. Also, cables should not rest on each other or be placed on
conductive surface while making voltage measurements.
Always observe proper safety precautions when operating high voltage
equipment.
