Digital Earth Resistance Tester GT5105A Electrical Tools​

This instrument is controlled by intelligent microcontroller chip, with high accuracy and high reliability; it can be used to measure grounding resistance of various power facilities wiring, electrical equipment, lightning protection equipment and other grounding devices, and it can also measure ground voltage. (Note: This instrument is not suitable for harsh outdoor environmental conditions, such as raining, lightning, etc.)

• 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.
• 1.1 Measurement range and measurement error
