Description

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.
