Safety Information

Caution! Refer to the explanation in this Manual

Double Insulation or Reinforced insulation

CE Compliance

This device must not be handled by children. It contains

hazardous objects as well as small parts that can be swallowed.

Do not leave batteries and packing material unattended; they

can be dangerous for children. If unused for an extended

period of time, remove the batteries from this device Expired

or damaged batteries can cause cauterization on contact with

the skin; use suitable hand gloves in such cases. Ensure that

the batteries are not short-circuited. Do not throw batteries

into the fire.

WARNINGS

•

Read understand and follow safety rules and operating

instructions in the manual before using this tester.

•

The tester’s safety features may not protect the user if not used

in accordance with the manufacturer’s instructions.

•

Check on a known live source within the rated AC

voltage range of the tester before use to ensure

it is in working order.

•

Insulation type and thickness, distance from

the voltage source, shielded wires, and other

factors may affect reliable operation. Use

other methods to verify live voltage, if there is

any uncertainty.

•

Do not use if the tester appears damaged or if it is not

operating properly. If in doubt, replace the tester.

•

Do not use on voltages that are higher than as marked on the

tester.

•

Use caution with voltages above 30 volts AC as a shock hazard

may exist.

•

Comply with all applicable safety codes. Use

approved personal protective equipment

when working near live electrical circuits

Operation

Power ON/OFF Button

•

Press the tester ON/OFF Button, the tester will beep once, and

the green LED and work light will illuminate to indicate that the

tester is working on high voltage mode and ready for use.

•

Press the ON/OFF Button one more time, the tester will beep

twice, and range LED will turn off.

Mode Select Function

•

When the tester is on with NCV function, short press the M

Button once, the green LED off and the yellow LED

illuminate to indicate that the tester is working on low

voltage mode.

•

Short press M Button again, the green and yellow LED flash

slowly alternately to indicate that the tester is working on

phase sequence test mode.

•

Short press M Button again, the yellow led off and the green

LED illuminate, the tester returns to high voltage mode.

•

The tester will beep once every M Button operation.

•

The M Button operation is valid only when the NCV function is

turned on.

Verify Operation

•

Before using tester, (1) Make sure the green LED is glowing, (2)

Check tester on a known live AC voltage that is within the

defined detection range of the tester.

High Voltage Mode (100 to 1000V AC)

•

Place the tip of the tester near an AC voltage.

•

If the tester detects voltage within the defined detection range,

the green LED will turn off, the red LED will turn on, the beeper

will beep rapidly.

Low Voltage Mode (12 to 1000V AC)

•

Place the tip of the tester near an AC voltage. When AC voltage

is detected, the yellow LED will turn off, the red LED will flash

and the beeper will beep.

•

The flash rate and beeping rate will increase as the tester gets

closer to the voltage source.

•

If the tester detects high voltage, it will automatically change

over to the high voltage mode: The red LED will change to a

steady glow and the beeper will beep rapidly.

•

Note: An indication occurs when the tester is used to detect AC

to DC power supply, for example, the phone USB

•

cable/line is being charged with a socket.

•

Note: The tester cannot determine the actual voltage. The

voltage level where the tester switches from the low to high

voltage mode is affected by insulation type and thickness,

distance from the voltage source, and other factors.

Phase Sequence Test Mode

•

Place the tip of the tester close to the L1 phase wire, the

tester will beep once, the green and yellow LED flash rapidly

alternately to indicate that the measurement of the first

phase sequence is complete.

•

Move the tip of the tester close to the L2 phase wire, when the

measurement is complete there will be two results:

1.The tester beep and green LED on about 5 seconds to

indicate that is Correct phase conformity (L2 is ahead of L1

120 degrees).

2.The tester beep and yellow LED on about 5 seconds to

indicate that is Incorrect phase conformity (L2 is lag of L1 120

degrees).

•

Test L1 and L3, L2 and L3 in the same way.

Note: To improve test accuracy, do not place the tester tip in the

middle of the two-phase lines

Auto Power Off

•

To conserve battery life, the tester will automatically turn off

after approximately 5 minutes of inactivity.

•

When powering down, the tester will beep twice and the mode

indication LED will turn off.

Flashlight

•

Momentarily press the Flashlight button to turn the flashlight

on or off.

•

To conserve battery life, the flashlight will automatically

turn off after approximately 5 minutes when the NCV

function is off.

•

The tester will beep twice as the flashlight auto power off.

Changing Batteries

1. Carefully unscrew

battery cap at the

rear (flashlight end)of

the tester.

2. Replace batteries

with two AAA 1.5V

batteries. Observe

polarity. Carefully

align cover with

tester as shown below.

3. Screw cover onto tester until it feels tight. Do not use

excessive force.

4. Verify operation by using the tester on a known live AC

voltage within the defined detection range of the tester.

**Note: When batteries are loaded for the first time, please

remove the white, rectangular security strip before

installing batteries.

**Note: When replacing the batteries,be sure to secure the cap

firmly to maintain IP67 water and dust protection. A loose or

overtightened battery cap may compromise water and dust

protection.
