Safety instructions
Warning
To avoid possible electric shock or personal injury：
l Please use this tester strictly according to this instruction, otherwise, the protection function provided by
tester may be affected。
l
Do not use if the power indicator is not on。
l
Before use, test on the known power to ensure that the product is good。
l When using this tester, there may still be voltage even if there is no sound or light alarm. The tester only
indicates the effective voltage when the AC voltage produces an electrostatic field with sufficient strength.
If the field strength is very low, the tester may not be able to detect it. The tester may be affected by the
following factors, including, but not limited to：
Shielded wire / cable、Thickness and type of insulation、Distance from the voltage source、Complete
insulating、Differences in socket design, etc.。
l Do not use if the tester is damaged or the tester is not working properly. Before use, check that the probe
is cracked or broken. If in doubt, please timely repair tester。
l
Please do not apply the rated voltage above the mark on the tester。
l
To test AC voltage above 30V, special care must be taken in case of electric shock。
l
Comply with local and national safety regulations。
l
Use proper protective equipment in accordance with local or national regulations。

3. AC voltage detection
The probe tester inserted into the power socket or close to the live wire，When the tester detects the AC
voltage signal, the induction voltage signal lamp flashes，According to the detected signal strength, the
tester can illuminate the corresponding signal intensity indicator (high, middle, low)，At the same time,
the buzzer sends out different alarm sounds。When the AC voltage signal is sensed, Low signal intensity
indicator is lit；When sensing a higher AC voltage signal，Light up the signal intensity indicator (middle,
low) at the same time；When the highest AC voltage signal is sensed, the signal intensity indicator (high,
middle, low) is also lit。
4. Zero/live wire judgment。
Try to separate the two wires to be detected as far as possible，Then close the wire with the probe of the
tester，If it is a socket, insert the probe into the socket，One of the strong signals detected by a tester is
live wire，a weak or no inductive signal is zero wire。
5. Auto Power Off
When the tester does not operate for about 5 minutes and the voltage signal is not detected, the tester
will turn off automatically。
6. Low battery indication
When the battery voltage is lower than about 2.6V, the power indicator flashes 3 times, and the buzzer
beeps and shuts off automatically. Please replace the battery in time。
