Introduction：          

Digital Earth Resistance Tester, also known as earth resistance tester, grounding pile type earth resistance, grounding megger, which is used for measurement of earth resistance and earth voltage.The tester adopt with digital and micro-processing technology, and the earth resistance is measured by precision 3-wire method or 2-wire method widely used in industries such as electric power, telecommunication, meteorology, oil field, construction,lightning protection and industrial electrical equipment.

Digital Earth Resistance Tester consists of host, test line, etc. The Tester has unique line resistance verification function, which makes the measurement of low-value earth resistance in the field more accurate, and can avoid errors caused by change in line resistance caused by long-term use of the test line; can avoid errors caused by the test line not being fully inserted into the tester interface or poor contact, as well as the errors caused by the user replacing or lengthening the test line, etc. The tester adopt with large LCD display, white screen backlight, and a bar chart indication, which is clear and obvious. It stores 400 sets of data, with maximum, minimum, and average indicator, and has functions such as historical data reading and reviewing.
Features:

1.Precision 3-wire method or simple 2-wire method to measure earth resistance.

2. The tester has unique line resistance verification function, anti-interference ability and environmental adaptability, and the earth resistance measurement is more accurate.

3. The host has large LCD display, white screen backlight, and bar chart indication, which is clear and obvious.

4. Alarm function, setting alarm threshold.

5. Memory, 400 sets of data storage.
