Digital Earth Resistance Tester GT5105A
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.)
Features of Digital Earth Resistance Tester:
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.
