OPERATING INSTRUCTIONS
2) Measure from one elbow test point to the other. This reading will show either a
high voltage reading indicating the elbows are out-of-phase or a zero or low voltage
reading indicating the elbows are connected to the same phase. The out-of-
phase measurement will likely not show the higher voltage expected from
a phase-to-phase measurement but will be closer to the line-to-ground
voltage. The in-phase voltage measurement can be between zero and 15%
of the nominal line-to-ground voltage. If both elbows are of different type and
manufacture, then a higher reading may occur.

PEAK HOLD

The DVM-80UVM includes a Peak Hold feature. To activate the Peak Hold feature
press the Peak Hold button. Peak Hold is indicated by all decimal points flashing.
The display will hold the highest reading while Peak Hold is activated. To deactivate
the Peak Hold and clear the display, press the Peak Hold button again.
Note: The meter will not shut off while a peak reading is displayed.

CARE AND MAINTENANCE

Periodic regular maintenance is required to keep the voltmeter in proper operating condition.
Keep the voltmeter clean and dry and always store it in its case. The fiberglass sticks
should be kept clean and free of dirt, contamination and marking. Examine the cord for
cracking or other damage prior to each use. Although we don't specify a calibration cycle,
we recommend you test, measure and calibrate your instrument annually. The Calibration
and Maintenance Log provided on page 15 can be used to record these events.
Contact HD Electric Company for details.
CLEANING INSTRUCTIONS: To clean the DVM-80UVM wipe with a damp cloth with water.
Do not use harsh chemicals or solvents.

PROBES AND ACCESSORIES

WARNING:
ALWAYS use probes appropriate to your application. NEVER use overhead
probes in underground applications. Failure to use the correct probe can result in arcing
or electrical contact and may cause serious injury or death. If you are not trained in the
particular operation or are not sure about the appropriate probe for your application
DO NOT PROCEED.
The DVM-80UVM comes standard with two overhead hook probes (025-OLPS-5), a
9-volt battery, instruction manual and a carrying case (CS-DVM). The DVM-80UVK
Universal Voltmeter Kit is supplied with a DVM-80UVM dual stick phasing voltmeter, two
overhead hook probes (025-OLPS-5), two resistor sticks (R-80), two underground bushing
probes (ASP-15/25), an underground cable fault tester (CFT-35), voltmeter proof tester
(PT-5000B), two shotgun hot stick adapters (HSA-2500), a 9-volt battery, instruction
manual and a soft-sided carrying bag (B-12). The following pages describes these probes
as well as other optional probes and accessories available.
