Light Switch
Easier-To-Read, illuminated Dial
• The lighted-dial option sets this unit apart from standard
features on Multi-Range Voltage Detector (MRVD)
C4030979, shown on next page
• A long-life bulb, powered by included internal battery,
gives a glow to the meter face so scale is easy to read in
most conditions
• To conserve the battery, a special switch locks the light
off when not in use
• Spring-loaded toggle must be pulled up to move it over
the stop between its on and off positions
• This helps keep switch from being flipped on accidentally
while unit is not in use
Standard Features
• Confirms a line is de-energized prior to performing
maintenance
• A field intensity meter, it is calibrated to read
approximate line-to-line voltage when connected to any
phase conductor
• Responds to magnitude of field gradient between its end
probe and floating electrode (at the universal hotstick-
attachment fitting)
• If the universal fitting is close to a ground, another phase
or another voltage source, reading should be high
• If it’s close to a jumper or equipment of the same phase,
the reading should be low
• Gives metered readout capable of distinguishing actual
line voltage from static or feedover from an adjacent line
• Numerical readings can be compared with numerical
rather than subjective judgments associated with “fuzz
sticking” or “glow-detecting”
• Since it is not a voltmeter, no specific accuracy is claimed
by the manufacturer or can be assumed by the user
Operation
• Must be mounted on proper length hotstick for the
voltage class involved
• Complete instructions are furnished with easy, illustrated
step-by-step procedures
• Internal circuit and pushbutton permit check before
and after each use to confirm operational condition of
instrument and battery
Includes:
• Straight probe for URD elbows with test points
• Hook probe for overhead uses
• Instructions and storage case
