SAFETY
Please read the safety instructions provided in the separate
booklet with the device.
Test device on a known live circuit before use to ensure the
device fuctions properly.
Before using this tester,even there’s no sound or light alarm,
voltage may still exist.The tester only indicates the valid voltage
when there’s AC voltage generating electrostatic eld with
sufcient intensity. If the electric eld intensity is very low, the
tester may not detect.
NOTE
Be extra carefull when measuring voltages over AC 36V to
avoid electric shock.

BATTERY
This device uses 2 Alkaline 1,5 Volt AAA batteries. Inserted in the
back of the device by unscrewing the cap [04].
When the battery is low, the power indicator will ash three
times while the buzzer sounds.
Replace the battery as soon as this happens.
FIRST TIME USAGE
Remove all plastics from the device before using and insert the
batteries that came with the device.
USE
TURNING ON/OFF THE DEVICE
·To turn on the testing device, press the power button [B].
All the devices’ indicators and buttons will ash once to indicate
that the device is on and functioning.
·Press the power button [B] again to turn off the device.
NOTE
The device will remain on stand-by mode once turned on for
5 minutes, even if there are no lights indicating it, the device
is turned on!
TURNING ON/OFF THE FLASHLIGHT
The voltage detector has a built-in ashlight that allows the user
to work safely and accurately in darker spaces.
·To turn on the device’s built-in ashlight, press the ashlight
button [C].
·Press the ashlight button [C] once more to turn off the
ashlight.
AC DETECTION RANGE SELECTION
The Voltage Detector has multiple ranges in which it can detect
voltage. The default range will always be 48~1000V.
·Press the AC voltage range selector button [D],the button will
light up and the range will be switched to 12~1000V
·Pressing the button [D] again will reset you to the default
range, the light turns off again.
AC VOLTAGE DETECTION
Using the probe [01] of the tester, we can check if a wire or
power socket is live.
·Insert the probe [01] of the tester into power socket or get
close to the live wire.
When the tester detects an AC voltage signal, the induced
voltage signal indicator [03] ashes, and the tester lights up
corresponding signal intensity indicator[A] according to the
detected signal intensity.
Low Green ashes - Medium Green continuous -
High Red continuous.
The buzzer makes alarming sounds of different frequencies.

NEUTRAL LINE / LIVE WIRE DISTINCTION
Before we can judge which of two wires is the live/neutral wire,
we have to separate the wires as far as possible.
·Hold the probe [01] close to each wire or insert it in the
socket.
·Check what subject has the highest induced signal strength.
This will be the live wire.
·The subject with the lowest/no signal strength is the neutral
line.
