- Electric test pen– ac test: hold the contact probe with your hand and use the pen tip touch neutral line/live line/ground line. the light will on when touching live line, no light or dim light when touching neutral line.
- Tester screwdriver– self-test function usage: self-test before use, hold the pen tip in one hand, and touch the touch electrode with the other hand.
- Live wire detector– applicable: line on-off detection, line breakpoint test, neutral line/live line detection, dc detection, sensing function.
- Electric pen– dc test: hold the contact probe with one hand, touch the positive pole of battery with pen tip, hold battery negative pole with another hand. the light will on means sufficient battery level, dim lighting/no lighting means insufficient battery/out of battery.
- Voltage sensitivity pen– self-test result: when the light is on, it means that the electric pen is normally fully charged, and if it is not on, it means that the battery needs to be replaced. through the human body circuit, the luminescent lamp will emit red light.
