Read all instructions before using the appliance and retain for future reference.
• Please follow all safety operation instructions.
• Check probes and case insulation before using. If you find any breakage
or abnormality, or you consider the device is broken, stop using the device
immediately.
• Test using a known live source in the AC voltage range to confirm the tester is
working properly before use.
• Use caution with voltages above 30VAC as a shock hazard may exist.
• Insulation type and thickness and other factors may effect the operation, use other
methods to verify live voltages if there is any uncertainty.
• Do not use the product for any purpose other than that for which it is designed.
• Turn the tester off when not in use to save the battery.
• Remove the battery if the meter is not to be used for long periods.
• Replace the battery as soon as the low battery warning appears to avoid possible
electric shock or personal injury caused by incorrect readings.

• Turning the tester on: Momentarily press the tester On/Off button (5). The
sounder will beep once and the green LED will illuminate to indicate that the tester
is on and ready for use.
• Turning the tester off: Momentarily press the On/Off button. The tester will beep
twice and the green LED will turn off.
• Turning the sounder off: With the tester off, press and hold the On/Off button until
the green LED is illuminated. The tester will now operate without the sounder. To
turn the sounder off when the tester is on, press and hold the On/Off button until the
green LED flashes. To turn the sounder back on, press and hold the On/Off button
until the green LED flashes and the sounder beeps.
• Verify Operation: Before using tester, make sure the green LED is glowing and
check the tester on a known live AC voltage that is within the defined detection
range of the tester.

CLEANING
• Clean the tester with a clean, soft cloth.
• Do not use any chemicals, abrasives or solvents that could damage the tester.
MAINTENANCE
1. Carefully unscrew the battery cap at the rear (flashlight end) of the tester.
2. Replace the batteries with two AAA 1.5V batteries observing the polarity.
3. Carefully align the 2 flashlight contact springs on the cap with the contacts above
the batteries.
4. Press the cover onto tester and rotate clockwise until engaged. Do not use
excessive force.
5. The IP67 dust and water ingress protection level is
determined by the correct fitting of this cap.
NOTE: When batteries are loaded for the first time,
please remove the white, rectangular security strip
before installing the batteries.
• High Voltage Mode (200 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, and the sounder will beep rapidly.
• Low Voltage Mode (12 to 1000V AC): Press and hold the 12V button (4). The
green LED will change to yellow to indicate the tester is in the low voltage mode.
While pressing the 12V button, 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
sounder will beep.
NOTE: 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 sounder will
beep rapidly. The tester cannot determine the actual voltage. The voltage level where
the tester switches from the low to high voltage mode is effected by insulation type and
thickness, distance from the voltage source, and other factors.
• Low Battery Indication: Replace the batteries if the green LED does not turn on.
When the tester is on and the batteries are too low for reliable operation, the beeper
will beep three times and the green LED will turn off indicating the tester is not
operational. Replace the batteries to restore operation.
• Auto Power Off: To conserve battery life, the tester will automatically turn off after
approximately 5 minutes of inactivity. When powering down, the beeper will beep
twice and the green LED will turn off.
• Flashlight: Momentarily press the Flashlight button (3) to turn the flashlight
on or off. To conserve battery life, the flashlight will automatically turn off after
approximately five minutes. The beeper will beep twice as the flashlight turns off.
NOTE: If the battery voltage is too low to operate the flashlight, the tester will indicate
this condition by beeping three times and the flashlight will turn off. The voltage detector
has it’s own low battery threshold and may remain operational, verify it’s condition before
using the tester.
