Check Fuses
Turn ON the mains to the fuses. Run the probe across the fuses. A dead
fuse is indicated when the Detector stops responding.
To Identify The Live Slot On An AC Outlet
Insert the probe into each slot of the AC outlet. The one with the
stronger signal is the “live” slot.
To Check Safety Grounding Of Power Tools Or Appliances
Connect the equipment to the mains. Place the probe in contact with
the metal housing. If no signals occur when equipment is switched on
and off, then it is safety grounded.
To Check Continuity On DC Circuits (3V or Up)
Remove cap from probe and place probe in contact with the circuit.
Place free hand on ground connection of circuit. The indicators will be
triggered if voltage exists.
To Check Auto Accessories
Detector can quickly find the source of current failure to the ignition
switch, lights, or other accessories. Remove cap from probe and touch
probe to the accessory while placing the free hand on the car body. If
no response occurs, then the failure is in the accessory.

Periodic service
WARNING!
Repair and service of this instrument is to be performed by qualified
personnel only. Improper repair or service could result in physical
degradation of the instrument. This could alter the protection from
electrical shock and personal injury this meter provides to the
operator. Perform only those maintenance tasks that you are
qualified to do.
These guidelines will help you attain long and reliable service from
your meter:
1. Calibrate your meter annually to ensure it meets original
performance specifications.
2. Keep your meter dry. If it gets wet, wipe it dry immediately. Liquids
damage electronic circuits.
3. Whenever pra c t i cal, keep the meter away from dust and dirt, which
can cause premature wear.
4. Although your meter is built to withstand the rigors of daily use, it
can be damaged by severe impacts. Use reasonable caution when
using and storing the meter.
Cleaning and Decontamination
Periodically clean your meter’s case using a damp cloth. DO NOT use
abrasives, cleaning solvents or strong detergents, as they may damage
the finish or affect the reliability of the structural components.
Introduction
The UTL7002 pocket-clip voltage detector sounds off with a loud tone and
lights its LED indicator when it’s held near an AC voltage source. It can also
be used as a quick “contact” DC detector for voltages as low as 3 volts DC
with plastic cap removed.
Features include
• Detect live voltages (50 to 500 ACV and 30 to 220 DCV)
• AC and DC voltage detection
• Batteries included (AB13)
Safety Notes
Before using this detector, always test on a known voltage source to
make sure it is operating properly. Do not remove the cap from the
probe when detecting voltage over 250 volts.
WARNING!
Exceeding the specified limits of this meter is dangerous and can
expose the user to serious or possibly fatal injury.
• Rubbing or banging the detector may generate static electricity and
cause a false reading
• Because of its sensitivity to extremely small currents, a false
reading may occur in some situations, e.g. a conductor with poor
insulation touching a damp wall will show voltage across the damp
area, indicating a potential hazard. A voltmeter should be used to
check the problem.
• Keep your fingers away from the test lead metal probe contacts
and bus-bars when making measurements. Always grip the
instrument and test-leads behind the hand guards (molded into
the probes).
• In the event of electrical shock, ALWAYS bring the victim to
the emergency room for evaluation, regardless of the victim’s
apparent recovery. Electrical shock can cause an unstable heart
rhythm that may need medical attention.
Operating Instructions
Before use, push the Pen Clip (On/Off Switch) toward the probe. When
detecting AC or DC current, gently press and hold the Pen Clip, making
contact with the metal plate.
Detecting Breaks In Cables Or Appliance Leads
Move the probe along the cable. A break is indicated at the point where
the LED and buzzer cease to respond.
To Locate A Live Wire In Flat Cables
Hold the cable in one hand and point the probe tip toward it. The side
which causes the strongest response from the detector contains the
“live” wire.
