The WADFOW Test Pencil WTP2901 identifies live AC voltage between 100V and 500V. With a 3x140mm slotted tip, it makes contact with terminals to trigger the internal neon indicator. This tool verifies circuit continuity in household wiring or industrial panels.
Place your finger on the metal top cap while touching the tip to a wire. This completes the circuit through the internal resistor for a safe voltage check.
This tool detects alternating current between 100V and 500V. It won't provide readings for low-voltage DC batteries or dead lines.
