WADFOW WTP2901 Electrical Tester Screwdriver

Voltage Tester Screwdriver WADFOW WTP2901
An essential tool for electricians and general users needing to verify whether electrical current is flowing through wires, outlets, or electrical equipment. The screwdriver features a simple yet durable construction, consisting of a metal tip to contact the test point, an internal resistor, a miniature neon indicator bulb, and a metal contact point at the end of the handle. When the screwdriver tip touches a live wire and a finger contacts the metal plate at the end of the handle to complete the circuit, the internal neon bulb illuminates to indicate the presence of electrical current.

Features
- Test voltage: AC 100-250V
- Screwdriver tip size: 3x140 mm (slotted type)
- Display: Neon light illuminates when current is present
- Design: Compact size, easy to use, convenient to carry

How to Use
- Hold the screwdriver: Hold the test screwdriver with one hand, placing your thumb or index finger on the metal cap at the top of the handle.
- Touch the test point: Place the metal tip of the screwdriver onto the point you want to test for live electricity (e.g., socket hole, stripped wire, conductor).
- Observe the light: If electric current is present at the contact point, the neon indicator inside the screwdriver will light up. If there is no current, the light will remain off.

Precautions
- Do not use while the body is wet: Using a voltage tester screwdriver with wet hands or body may cause an electric shock hazard.
- Do not use as a standard screwdriver: The voltage tester screwdriver is not designed for tightening screws; improper use may damage the screwdriver or cause danger.
- Check before use: Before actual use, test the voltage tester screwdriver on a known live power source (such as a properly functioning outlet) to ensure it works correctly.
- Not a measuring instrument: The voltage tester screwdriver is only used to detect the presence of electrical current; it cannot accurately measure voltage, current, or resistance values.
- Caution with high voltage: Although the test voltage range is specified, use with extreme caution in high-voltage areas.
- Wear shoes: Always wear electrically insulated shoes when performing electrical work.
