FAQs

Can I use this for car battery testing?

No. This tester is designed for 100-250V AC circuits and will not function on low-voltage DC automotive batteries.

Do I need to change batteries?

No, this is a passive tester that does not require batteries to function.

Is the blade magnetic?

No, the blade is not magnetic and is specifically designed for testing purposes rather than driving screws.

What is the primary safety feature?

The primary safety feature is the TUV and GS certification, alongside the insulated blade design.

Can this identify which wire is neutral?

This tool is used to identify the 'live' terminal. It will not illuminate on the neutral or earth wire.

Troubleshooting

Indicator light does not glow when testing a live wire

Ensure you are making firm contact with the conductor and that your finger is in contact with the metal end cap on the handle.

The tool feels loose or damaged

Cease use immediately. Do not attempt to repair the internal electrical circuit; replace the unit.

Setup, Compatibility & Care

This tester requires no complex setup; it is ready to use immediately out of the packaging. It is compatible with standard 100-250V AC 50Hz mains electrical systems found in most residential and light commercial environments.

To maintain the tool:

  1. Keep the transparent handle clean to ensure visibility of the indicator light.
  2. Store in a dry, cool environment to prevent moisture buildup in the casing.
  3. Inspect the insulation layer before every use; if the blade insulation is chipped or cracked, the tool should be replaced immediately.
  4. Avoid using the tool as a heavy-duty screwdriver, as this may damage the internal testing mechanism.
