peak reading voltmeter
Part No. 085-111S
Output Voltage: Peak Reading Voltmeter
Available for Rent: $12.00/Calendar Day
The D.E. Stearns Company 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. Measurement can be made of peak values with rise time of less that one millionth of a second.
The Model PRM Voltmeter is portable and is ideal for use in the field or laboratory, for measuring the output voltage of spark type HOLIDAY DETECTORS.
The Model PRM may be used with the DE Stearns Model 10/20 and 14/20 Holiday Detectors.
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. Absolute Modularized Solid State construction assures dependability and virtually eliminates maintenance.

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 assure you of obtaining proper and expeditious service.
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 place on conductive surface while making voltage measurements. Always observe proper safety precautions when operating high voltage equipment.
Voltage Testing Procedures
A. Connect one of the two high tension cables, supplied with the voltmeter, between the dome top terminal of voltmeter and the high voltage output of the Holiday Detector.
B. Connect the other high tension cable between the ground post of the voltmeter and the ground terminal of the Holiday Detector. C. After properly connecting cables (see note below) turn Holiday Detector "ON".
D. Turn the control knob on the voltmeter to the positive (+) position and observe the meter reading if the meter reading does not closely correspond to the factory marking of the Holiday Detector turn the control knob to the negative (-) position. The meter reading must be within 10 percent of the factory markings on the Holiday Detector in one or the other polarities, otherwise there is a fault in one or both instruments. Note: It may be necessary to use the cables supplied with the Holiday Detector in conjunction with those supplied with the Voltmeter because the terminals vary on different Holiday Detectors. For example: Connections can be made directly to the ground wire and high voltage cable of the Holiday Detector to facilitate proper electrical connections.
Turn control knob to "Bat." position. Battery should read minimum of 6.0 volts. Replace if needed with fresh 6 each 1-1/2 volt "AA" Cell Batteries. NOTE: Do not store Voltmeter with batteries in place for long periods of time.
Maintenance and Service
Always store Voltmeter in Carrying Case. Do not expose to excessive moisture (keep dry) and clean. For factory service, send complete instrument freight prepaid to:
