How to use

To use the voltage tester screwdriver, ensure the device and your hands are dry and that you follow appropriate safety procedures. Insert the metal tip into the contact or place it against the conductor you wish to test while holding the insulated handle. Observe the tester's indication (visual or other marked signal) to determine whether voltage is present. Do not use the tool on energized equipment beyond its intended testing scope and avoid applying excessive force to contacts or live parts.

Recommendations

Use this tester for quick presence/absence voltage checks and routine inspections. For detailed measurements, high-voltage systems, or precision diagnostics, use a suitable certified multimeter or contact a qualified electrician. Regularly inspect the insulation and tip for damage and replace the tool if any wear that could affect safety is observed.
