1. Safety Rules
The safety voltage detector 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. The following rules should reduce
the danger:
● Read the user manual carefully and completely
before using the safety voltage detector. 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 safety voltage
detector.
● The safety voltage detector must never be in
physical contact with any conductor higher
than 1kV. This is a proximity detector, not a
detector which works by contact.
● Always check that the safety voltage detector
is working before and after the test.
This instrument should only be used by a
competent, suitably trained person who
understands this test procedure fully.
Personnel working with high voltage Should
be trained regularly.

2. General Description
The safety voltage detector is a new instrument
for checking the presence of AC voltages.
The safety voltage detector detects AC voltages
using the sensor plate. The sensor plate collects
part of the radiated electric eld (V/M).
The safety voltage detector works by proximity.
Its sensor senses the radiated eld which
surrounds live conductors.
This is an instrument designed to alert users
that they are approaching live equipment where
dangerous voltage is present.
The safety voltage detector helps the user
stay a safe distance away from live equipment.
It therefore protects and safeguards users
from approaching dangerous live high voltage
equipment or cables.
It's a new tool for checking the presence of AC
high voltages and low voltages. The voltage
detection is from 100Vac to 50kVac.

6. Method of use
Important:
It's necessary to put the safety voltage
detector into the soft pouch for voltage
detection. Please remember to put the 302
SVD into the soft pouch before doing the
voltage detection.
● CHECKING AND PROOFING
Turn the ON/OFF switch to the ON position,
then press the SELFTEST button, the buzzer
of the safety voltage detector should beep,
and the LED indicator should light.
This indicates that the safety voltage detector
is operational.
Turn the ON/OFF switch to the ON position.
Verify the working of this safety voltage
detector by placing the unit against a low
voltage live conductor. The LED indicator and
the buzzer should go on.
● OPERATION
Turn the ON/OFF switch to the ON position for
the non-contact voltage detection.
-8-
The safety voltage detector should always be
on the outside of any clothing.
For example, the safety voltage detector has
to be in the soft pouch, put the safety voltage
detector on your chest with the shoulder belt
around your neck. Please see g1.
