General Description - Textron HD Electric DVM-80UVM Operating And Instruction Manual

GENERAL DESCRIPTION

The DVM-80UVM is a high accuracy digital voltmeter and phasing set designed to measure
voltages up to 40kV and up to 80kV when used with a pair of add-on resistors. The
DVM-80UVM includes an elbow test point reading feature as well as a peak hold
feature. The DVM-80UVM can be purchased on its own or in a complete, ready-to-
use Universal Voltmeter Kit that contains the following probes and accessories:
DVM 80UVK UNIVERSAL VOLTMETER KIT
• Dual stick phasing voltmeter (DVM-80UVM)
• Two overhead hook probes (025-OLPS-5)
• Two resistor sticks for measurements up to 80kV (R-80)
• Two underground bushing probes, 15 and 25kV class (ASP-15/25)
• An underground cable fault tester, 15, 25 and 35kV class (CFT-35)
• Voltmeter proof tester (PT-5000B)
• Two shotgun hotstick adapters (HSA-2500)
• A soft-sided, multi-functional carrying bag (B-12)
See pages 9-14 for a complete list of probes and accessories available.
All HD Electric voltmeters and phasers are constructed with epoxy encapsulated high
voltage resistors, a connecting cord and a meter display. The DVM-80UVM is a digital
meter. The major elements are shown here:

Stick
The high voltage resistors limit the current through the connecting cord to less than one
milliamp. Although the connecting cord is insulated for voltage up to 10kV, it should
always be kept free and clear from you, ground and any other conductors. These
instruments will measure DC through 1000Hz RMS AC.
WARNING: The DVM-80UVM will require add-on resistor sticks for higher voltage ranges.
Always completely remove the voltmeter from the live circuit before adding or removing
add-on resistor sticks. Always use add-on resistor sticks in pairs, one on each voltmeter stick.
