STANLEY 66-119 Voltage Tester Screwdriver Test Range 100-500V Size 127mm

Voltage Tester Screwdriver STANLEY 66-119 test range: 100-500V test range Size 127 mm
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.

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.
