Test Kit with Multimeter, Non-Contact Volt Tester, Receptacle Tester


  • Multimeter measures up to 600V AC/DC voltage, 10A DC current and 2MΩ resistance
  • Non-Contact Voltage Tester Cat. No. NCVT1P has a bright green LED to indicate the tester is working; it changes to red and audible tones sound when a voltage is detected
  • NCVT1P has a high-intensity, bright red LED that illuminates and an audible tone when a voltage is detected from the 50 to 1000V AC power operating range
  • Receptacle tester detects wiring configurations and indicates correct wiring, as well as identifying common wiring faults
  • Identifies open ground, open hot, open neutral, hot/ground reversed; it does not indicate quality of the ground, multiple hot wires, or a combination of defects
  • MM300 multimeter tests continuity with visual and audible continuity indicators
  • Test leads included for Cat. No. MM300; batteries included for Cat. Nos. NCVT1P and MM300
