• 3 Modes for continuity and voltage testing:
  Mode 1: Continuity tester for unpowered circuits. 0-10 ohms, uses lamp with batteries
  Mode 2: Voltage tester 60-600 volts AC or DC when lamp is used without batteries
  Mode 3: Voltage tester 0-60 volts AC or DC when various lamps are used without batteries
  
• Range: 0-600 volts or 1-10 ohms
• Probe voltage: 3 volts at 270 ma maximum
• Low voltage lamp tests unpowered circuitry
• Illuminated lamp is easy to confirm electrical circuit continuity
• High voltage lamp tests live circuitry

Tests continuity on dead circuits and voltages from 2V to 500V AC or DC. Indicator lamp at tip allows you to keep eyes on probe. Comes with two interchangeable bulbs for low-voltage (0 to 70V) and high-voltage testing (60 to 500V). Features a high-impact molded body with 3 ft. lead, fitted with insulated alligator clip. Operates with two AAA batteries (not included).
