• Digital Earth Resistance Tester possesses the following features:
  

  1.backlight and battery detection function.

  2.data holding.

  3.It can be used for precise three-wire measurement or simple

  two-wire measurement.

  4.When measuring ground resistance, if C or E end of test lead is

  not in good contact, "---- Ω" warning appears on LCD.

  5."OL" stands for over range.

  6.Double insulation or reinforced insulation safety structure.
