    • Selectable loads of 12, 15 and 20 Amps
    • Measures loaded and unloaded AC Line Voltage
    • Calculates and displays % Voltage Drop and Line Impedance
    • Displays Peak Line Voltage and Frequency
  • Outlet Tester functions:
    • Neutral to Ground Voltage
    • Hot, Neutral and Ground Impedance
    • GFCI Trip Time and Trip Current
    • Open or Reversed wiring
  • Complete with AC test cord (standard North American 3-prong plug)
