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。
