Digital Earth Resistance Tester GT5105A<\/h1>\n
\n
\n
\n
\n
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.)<\/div>\n
\n

Digital Earth Resistance Tester possesses the following features:<\/p>\n

1.backlight and battery detection function.<\/p>\n

2.data holding.<\/p>\n

3.It can be used for precise three-wire measurement or simple<\/p>\n

two-wire measurement.<\/p>\n

4.When measuring ground resistance, if C or E end of test lead is<\/p>\n

not in good contact, “—- \u03a9” warning appears on LCD.<\/p>\n

5.”OL” stands for over range.<\/p>\n

6.Double insulation or reinforced insulation safety structure.<\/p>\n
