INTRODUCTION
325 SVD is a sensor for sensing AC High
Voltage. It provides electric engineering
personnel, power engineering personnel,
reghting personnel and instrument
equipment workers with prominent warning
when approaching high voltage and for taking
necessary safety action, preventing illusion and
misjudgment which could lead to electric shock
to person.
When a person wearing 325 SVD is
approaching high voltage source or equipment,
the sensor will detect automatically and buzzer
will generate a "BeBe" sound for warning and
LED will ash to remind operators that the
user is approaching a high voltage sauce and
special attention shall be given to the safety of
operations.

FEATURES
● Designed for detecting un-shielded cables. If
the shielding of the cable is connected to the
ground, it can't work.
● Compact, easy to wear and convenient in use.
● Designed for indoor and outdoor use.
●Water-proof design. (IP65)
● Equipped with self-testing functions.
● Able to sense all kinds of AC High Voltage
System.
● Low power consumption.
●Meets : EN61326-1.

METHOD OF USE
● Inspection before use
(1) Check the appearance and structure for
any abnormality.
(2) Press Self-Test switch (about 3 seconds)
to conrm all functions are working
normally.
(3) To be careful and to avoid misjudgment,
test the unit by contacting AC 110V
insulated wire with its front side to see if it
sounds and ashes.
● Wearing
Wear the unit on the outer side of the wrist
with the sensing side facing outward, as
shown in the following gure.
※The e󰀨ect is best when the sensing side
is facing high voltage at right angles (90
degrees).

CLEANING & REPLACING BATTERY
1.Sensing side shall maintain clean. The case
may be cleaned with soft fabric and mild
detergent. No solvent or corrosive agent may
be used.
2.Replacing battery
(1) When the sound become weak, the battery
shall be replaced.
(2) Use coin to open battery cover and
remove used battery. Place new battery
into slot with the battery positive (+) face
up and fasten battery cover with coin.

CAUTIONS
1.This instrument is an auxiliary testing unit and
is only for obtaining warning as additional
protection. Never use this instrument as
substitution for Tester. Electrical Test shall be
the prime electric testing instrument.
2.Other than a󰀨ected by now you wear, the
sensing and warning distance may be
inuenced by direction of electric article,
ambient environment, shielding objects and
weather conditions.
3.Buzzer has inner water-proof lm. Do not
pierce it with sharp article.
4.Do not store this instrument outdoor or inside
of car for long time to avoid direct sunbeam
and high temperature.
5.The instrument shall not be dropped or
impacted heavily. If such situation does
happen, perform inspection and self-test to
ensure no damage occurred before using
again.
6.If the instrument is rinsed by rain, remove
battery and place it at cool place for natural
dry.
