SAFETY RULES
The Personal Electrocution Guard (PEG) has been designed with
safety in mind. However, no design can completely protect against
incorrect use.
Electrical circuits are dangerous and lethal through lack of
caution or poor safety practice. Please follow safety rules to
reduce danger and practice safety.
You are advised to take note of the following important points;
• Read the User's manual carefully and completely before
using the tester. Fully understand the instructions before
using this product. Follow the instructions for every test.
Take all the necessary precautions. Do not exceed the
limits of this instrument.
• The PEG should never be in physical contact with any conductor
higher than 1kV. This is proximity detector. It is not a detector
which works by contact. As such, contact should be avoided.
• Always check that the PEG is working correctly before and after
the test (press both push button to verify the device is working
perfectly before using the testers to detect voltage and repeat
same after detection).
• Do not touch any exposed wiring, connections or other
"Live" parts of an electrical circuit.
• This instrument should only be used by a competent,
suitably trained person which understands fully this test
procedure. Personal working with High Voltage should be
trained regularly. Use Protective gear.
Caution, risk of electric shock.
Caution, refer to the user's manual.

GENERAL DESCRIPTION
The PEG consists of an internal pickup AC sensor plate, a test
(oscillator) and diagnostic circuit, an adjustable threshold
comparator, a sound annunciator (buzzer), a visual indicator
(super high bright led) and a 9V battery, all enclosed in the robust
"beeper" style case.
The enclosure has a built-in clip for easy attachment on the outer
garments / external clothing or belt.
PRINCIPLE OF HOW IT WORKS
The PEG detects AC voltages using its internal AC sensor plate.
The AC sensor plate picks up part of the radiated electric field in
volts per meter (V/M).
The electric field is amplified and processed by the internal
circuitry and once the processed signal is above the threshold,
triggers the input of a integrated circuit, which start the oscillators
for the buzzer and led.
The Buzzer beeps
and LED lits
intermittently at a
rate of 2 beeps
/flash per second.

CHECK IT AND GET IT GOING
After inserting the battery, close the cover. The tester will be ON
automatically.
1- Check the working of the voltage detector
Once the battery has been inserted, wait for a few seconds.
If no beep and no flash occurs, press simultaneously the 2
push buttons.
While the 2 push buttons are pressed, the internal 50/60Hz
oscillator will start oscillating (generates test signal) and this
signal will be connected to the sensor.
While pressing the 2 push buttons, the buzzer and the
led will function at a rate of about 2 beep/flash per second.
That indicate proper operation of the tester.
Release the push buttons, and wait for about 30 seconds. If
there are no other beep/flashes, that mean everything is correct
and it is ready for use.
2- Low Battery detection and indication
When the battery becomes to low, a beep/flash will happen
about every 5 seconds, Replace the battery immediately.
3- Sensitivity
Covering the voltage detector with any kind of obstructive
material could affect its sensitivity. It is advised to wear it
outside clothing, clipped on the belt or on the pocket. Please
note that the enclosure is static sensitive and can become
charged and thus alarm may be triggered by excessive static.

LOW VOLTAGE TESTING
Physical contact with electrical conductors is not necessary when
testing for Live Lines proximity.
This tester works by proximity.
Its sensor senses the radiated field which surrounds live
conductors.
It is recommended not to touch High Voltage wires with the PEG.
Radiated field strength increases with voltage and decreases
quickly with distance or earth shielding.
Detecting distance of a 240Vac single Live Wire is about 10cm.
FOR BEST RESULTS
The PEG should always be WORN ON THE OUTSIDE of any
clothing.
For example, clipped onto the pocket, belt or on the vehicle's
mirror.
The PEG could be sensitive to static build-up and may become
charged. In this case, this could trigger the alarm.
The PEG should be worn FACING THE DIRECTION OF
WALKING TOWARD THE SOURCE.
WHILE FACING THE SOURCE, THIS WOULD BE THE FRONT
OF YOUR BODY ( use the breast pocket ).
Always ensure that the alarm can be heard and seen (in case of
noisy environment, check the alarm sound again before use to
ensure you can be alarmed)

PREPARATION FOR USE
When unpacked, the tester should be inspected for any visible
signs of damage, and the preliminary checks described (depress
both push button for proofing the unit) should be performed to
ensure that it is operating correctly.
If there is any sign of damage, or if the instrument does not
operate correctly, return it to your nearest supplier.
This instrument is powered by one 9V type battery. Use alkaline
for best results.
CHECKING AND PROOFING THE TESTER
Depress both push button simultaneously. The Buzzer will beep
and the LED will flash twice per second if everything is correct with
the proofing of the voltage detector.

TYPICAL USES
Workers Safety.
Emergency services protection (fireman, evacuation personal,
police, etc...)
Safely identify HV source while approaching it.
The user has the PEG clipped on his breast pocket while
working/walking in a electrical environment. The PEG will alert the
user of any HV source near by and therefore the user will be able
to take protective action before being close to the H.V.
Identify and check AC live cables.
Check and Detect Live High Voltage Cables.
Neon lightning servicing.
Tracing live wires.
Detecting of residual or induced voltages.
BROKEN WIRES IN CABLES
Faults in damaged flexible cables are found by applying low
voltage to each conductor in turn, earthing the remainder and
moving the tester along the cable until the change in condition is
obtained (flexible cables as used in mining and building industries
are readily repairable when the break in the cable is located).
NON CONTACT ADVISE
It is advised that the tester should not come into contact with
cables (kV) as this tester is merely an Non-Contact A.C. Proximity
Tester.
This advise is particularly useful to protect users which do not
respect protection and safety rules and who do not wear protective
gear.
Never work or be alone in the proximity of high voltage.
-9-
LIMITATIONS OF THE PEG
It is recommended that this tester is not used in H.V. Yards of
mixed voltages. In the presence of mixed voltages, the user
will not be able to pin point exactly which cable is the source
of H.V..
This tester has been designed to be used as a personal
safety proximity voltage detector alarm.
This is not a measuring instrument.
Problems can be arose when the tertiary circuit of a
275/133/11kV transformer is tested. The electric field of the
H.V. And M.V. Bus bars can trigger the detector when it is
about 3m above the ground (this is common with most of the
electric field PEG and the users should be aware of it).
The tester could pick up adjacent circuit to the one being
tested and indicates the wrong information to the user.
REPLACING THE BATTERY
The PEG has been designed to have
a super low current consumption.
One alkaline battery could last up to one
year or even more (Depending on the
battery energy).
Once the low battery alarm is announced
( beeps and flashes every 5 seconds),
the battery should be replaced Immediately.
The PEG uses one 9V battery.
Remove the battery cover. Ensure
polarity is respected and replace
with a new battery. (Photograph
shows cover removed and new
battery inserted.
