    Product Introduction
    ETCR3000A+ 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.
    ETCR3000A+ Digital Earth Resistance Tester consists of host, test line, etc.The tester has the function of judgement the earth resistance of the auxiliary grounding pile. The tester can display the resistance value of the auxiliary grounding pile during testing, which can avoid error caused by the excessive earth resistance of the auxiliary grounding pole.with line resistance verification function that 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.It makes the measurement of low-value earth resistance in the field more accurate and reliable.
    1.Precision 3-wire method or 2-wire method to measure earth resistance.
    2.The Tester is lightweight, easy to carry, and operation convenient.
    3.The tester has the function of judgement the earth resistance of the auxiliary grounding pile. The tester can display the resistance value of the auxiliary earth pile during testing, which can avoid error caused by the excessive earth resistance of the auxiliary grounding pole.
    4.With line resistance verification function that can avoid the errors caused by the poor contact of test line, which makes the measurement of low-value earth resistance in the field more accurate and reliable.
