TesterMeter-ETCR3040 Digital Ground Resistance Tester

Introduction

ETCR3040 Digital Earth Resistance Tester is specially designed and manufactured for earth resistance and earth voltage measurement on-stie, which adopts digital and micro-processing technology,  measuring the earth resistance with precision 3-wire method or 2-wire method. The tester has the line resistance calibration  function, which can avoid the 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 replace or lengthen the test line, and make on-site low-value earth resistance measurement more accurate and reliable. The tester also has the auxiliary grounding pile alarm function, which can display the resistance value of the auxiliary grounding pile during testing, and the indicator light will show whether the auxiliary grounding pile is well grounded, avoiding the errors caused by excessive grounding resistance of the auxiliary grounding electrode. When testing the earth voltage, when the voltage larger than 36V will alarm to protect the safety of the operator.

ETCR3040 Digital Earth Resistance Tester is composed of host machine and test wires etc. With automatic shutdown function, the tester full range automatic shift, strong anti-interference ability, and easier operation. It is widely used in measuring ground resistance of electric power, telecommunication, meteorology, oil field, construction, lightning protection and industrial electrical equipment
