The document describes a voltage detector that detects AC and DC voltages through a long-life carbide tip. To use it, the user simply places the tip on an object, presses the trigger, and observes the LEDs - green means no voltage, red flashing means dangerous voltage is present. It is compact, lightweight, and easy to use to test potentially dangerous objects like electrical equipment to avoid electrical shock. It detects voltages as low as 50V AC or 6V DC and protects users from up to 20,000V AC or 2,000V DC.
