5. Operating Instructions
5.1 Power On/Off
- Press the Power Button (usually red) to turn the tester on.
- The tester will perform a self-test.
- To turn off, press and hold the Power Button, or the device will automatically shut down after 5 minutes of inactivity.

5.2 Sensitivity Selection (H/L)
The tester offers two sensitivity modes:
- High Sensitivity (H): Detects voltage in the range of 12V to 1000V AC. Suitable for detecting low voltage circuits or tracing wires.
- Low Sensitivity (L): Detects voltage in the range of 48V to 1000V AC. Suitable for standard household wiring and reducing false positives.
Press the H/L Button to toggle between high and low sensitivity modes. An indicator light or display will show the current mode.
5.3 Non-Contact Voltage Detection
- Ensure the tester is powered on and the desired sensitivity mode is selected.
- Bring the tip of the tester close to the wire, outlet, or electrical component you wish to test.
- If AC voltage is detected, the tester will emit an audible beep and/or a visual indicator (e.g., flashing LED). The frequency of beeps and flashes may increase with higher voltage or closer proximity to the source.
- Always test multiple points to confirm the presence or absence of voltage.

5.4 Infrared Pointing Function & LED Flashlight
The tester includes an infrared pointing function for precise targeting and an LED flashlight for illumination in dark environments.
- Press the Flashlight/Infrared Button (usually green with light/triangle icons) to activate the LED flashlight.
- Press the button again to activate the infrared pointing function.
- Press a third time to turn both off.
6. Maintenance
- Cleaning: Wipe the tester with a dry, clean cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
- Battery Replacement: Replace batteries when the low battery indicator appears to ensure accurate readings.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tester does not power on. | Dead or incorrectly installed batteries. | Replace batteries, ensuring correct polarity. |
| No voltage detection on a known live circuit. | Low battery, incorrect sensitivity mode, or faulty unit. | Replace batteries. Switch to High Sensitivity mode. If problem persists, the unit may be faulty. |
| False positives (detects voltage where none exists). | High sensitivity in an electrically noisy environment. | Switch to Low Sensitivity mode. Ensure no other strong electrical fields are nearby. |
| LED flashlight or infrared pointer not working. | Low battery or button malfunction. | Replace batteries. Ensure the button is pressed correctly. |
