SAFETY
•
Only trained, professional operating personnel should
use the DVI. The voltages this instrument operates at are
dangerous and lethal. Severe injury or death can occur
if improperly used.
•
Risk of electrocution is inherent in or around high voltage.
•
Always use proper high voltage procedures, including
personal protective equipment, when working near or
around high voltage equipment or conductors.
•
Do not exceed the DVI maximum voltage rating.
•
Assemble the DVI with the proper contact probe
for your application.
•
The DVI must be used with a hotstick of the
appropriate length for the voltage being measured
per your company and OSHA published requirements.
•
Do not touch the DVI during measurements. The DVI
housing should be considered to be at the same
voltage as the conductor under test.
•
Prior to using, inspect the instrument for any physical
damage, cleanliness and check for proper working order
by pressing and holding the ON button. Do not proceed
if the display does not indicate all
8’s
or if the beeper
does not sound.
•
Never allow another high voltage or grounded
conductor to contact the instrument during use. Keep
the DVI housing free and clear of all structures at all times.
Bridging the DVI probe or housing from line-to-ground
or line-to-line may cause a fault and arc.
•
The DVI does not indicate voltages below 100 volts.
Always use proper grounding procedures. A zero

voltage reading on the DVI
does not
mean the line
is dead or grounded.
•
Grounded equipment or lines can appear to be live
when in close proximity to energized conductors if
not fully or properly grounded.
•
Always test the DVI on a known voltage source
before and after each use, or use the PT-DVI Proof Tester.
•
The DVI is a voltage indicator, not a voltmeter.
Do not attempt to make accurate
voltage measurements for phasing or other applications with the DVI.
•
The DVI is a direct contact device. The metal portion of the DVI probe must contact the
metal conductor to be tested. Voltage indication on insulated conductors such as tree
wire or spacer wire will be much lower than actual and may not indicate any voltage at all.
•
DVI voltage readings are sensitive to geometry. Read and understand the Accuracy
section of this manual before using the DVI.
•
The DVI indicates AC voltage only. It does not detect DC voltage such as charged
capacitors or cable.
