  • Verifies if wiring is tested for load-carrying ability that it meets electrical code recommendations for voltage drop under load
  • Meter detects faulty wiring in need of repair without removing outlets cover plates or panel covers
  • User selectable 0, 10,15 and 20 amps loads to verify the performance of the electrical system
  • Incorrect wiring or voltage drop test failure is clearly indicated by flashing screen
  • Will not trip circuit breakers or blow fuses during the test
  • Tests GFCI and AFCI operations
  • Check ground quality for safety and ability to support sensitive electronic equipment
  • Measure fault currents
