Socket tester user manual
Socket tester are mainly used to detect polarity of power socket and
safety of leakage switch. It can quickly and accurately detect the wiring
of the socket. Simultaneously , it can test socket voltage and show on
the LED screen.

Warning
Please read this user manual carefully and obey safety rules and all
“warning”.
For avoiding possible body injury, please do following things：
· Please check the tester before use it, make sure it is good, if any damage,
please stop using and send to repair it.
·Check whether the tester is good , please put the tester on the known
right socket, use it after making sure test functions are all good.
· It can only be used normally if the wiring is correct .
·Please turn off all equipment When test leakage switch, make sure no any
damage will happen. Ask for allowing when test at the public.
· When it shows wiring is wrong, please ask for professional electrician to
correct it.
Technical Parameters
1. Instructions:
1）LED screen；
2）Power button；
3）RCD test indicator
light；
4）RCD test button；
5）Warning label: warn you it
will cause RCD cut off to press
this button. Check details
in the point 5.
2.LED screen introduction：
1）Low power symbol：prompt low power ；
2）High voltage symbol：prompt high voltage ；
3）Neutral wire symbol：prompt neutral
wire status；
4）Wiring correct prompt；
5）Wiring wrong prompt；
6）NCV symbol：NCV test；
7）NCV power intensity
indicator ；
8）Earth wire: prompt earth
wire status；
9）Direction symbol：the two
adjacent wires are reversed,need to be exchanged；
10）Live wire symbol：prompt live wire status ；
11）Shows the voltage between live wire and neutral wire ；
12）Shows the voltage between earth wire and neutral wire .
3. Turn on
1) Please open the back cover and put into 2 1.5V AAA batteries before turn it on;
2) Long press the power button to turn on the product.
4.NCV test
1）Please test the known electric line function are good before NCV test;
2）It is in the NCV test mode when turn on it.Hold the product and move it around,
the built-in beeper will beep when the inner sensor detects AC voltage nearby. The
stronger the voltage is, the quicker the beeper beeps while the central LED light will
twinkle. And lower right screen it shows the power intensity bar.
5. RCD test
Warning: please turn off all electrical appliance and make sure you are allowed. Please
make sure no any damage.
Put the tester in the right 3 holes socket and press RCD button (less than 3s), then the
normal RCD will trip, and it means RCD fail or missing if it doesn’t trip. Please ask for
professional electrician.
