Identification of Null and Live Wire
Keep the two lines (cables) as far away from
each other as possible. Then pay attention to the
signals:
Live Wire
Null Wire
Up to 8 var graphs on

Below 6 bars graphs on

Fast-paced beeping
signals
Slow-paced beeping
signals
Red screen
Green screen
If the voltage is higher than 90V AC, the screen
turns red and shows the high voltage symbol.
Note: Do not distinguish neutral and live wire
through the screen color, but through the
detected signal intensity. The live wire causes
stronger signals than the neutral wire.
Consequently, it is recommend to use the high-
sensitivity mode during identification.
Breakpoint Testing of Cables:
Put the device in high-sensitivity mode and move
the tester’s tip along the cable. The visual and
audio signal of the device will change/disappear
when a break is detected in the cable. Do not
use it on cable ducts or metal-clad cables.
LED Flashlight
Press the Sensitivity / Flashlight button and hold
it for more than 2 seconds to turn the flashlight
on or off. It will turn off after 3 minutes if no
signals or operation has been detected.
Auto Power off
After 3 minutes of inactivity and no signal
detection, the device will power off to save
energy.
Low Battery Indication:
When the battery voltage drops below 2.5V the
will be displayed. When the battery voltage
drops below 2.3V the device will automatically
turn itself off.
