Place two AAA alkaline batteries into unit and replace the battery cover as indicated in figure
Before each use, make sure tester work properly by testing a known working circuit that is within the
When the tip of tester lights, it means voltage exist, if no any indication, voltage could still be exist. (In case of the batteries going to be exhausted, the tester will not work properly, please replace new batteries)
When the tip of tester is near to live wire (L) or the hole L of a socket, red light appears in the top of tester. In this way the presence of AC voltage can be checked
Always keep your finger away from the white part of the tester when testing. (However you can put another hand on the object's insulated surface near to the probe to avoid static misleading wrong indication)
Do not rely on this unit in case of work on shielded wire. Operation may be affected by difference in socket design, insulation thickness and type
