3/4 Wire Digital Earth Ground Tester 572

Advanced Earth Resistance Tester

The 572 is an Advanced Earth Resistance tester based on 2/3/4 wire test measures earth resistance and soil resistivity. The instrument features detection of interference voltage/ frequency & automatic connection check to allow use in demanding conditions typical in high voltage power installation.

The 572 earth tester & soil resistivity tester has 5 operating range such as 4Ω / 40Ω/ 400Ω/ 4kΩ/ 40kΩ. The equipment comes with data hold feature & stores 20 sets of data for further access.

The 572 Digital earth Tester has Compensation Lead Resistance Test ( RK Test) feature to check the resistance of lead wire & make it negligible to get the actual resistance value of earth.

The 572 earth tester is for users demanding high precision & reliability.

The 2-wire test is a simple 2-wire test by taking the grounding electrode of known minimum grounding as the auxiliary grounding electrode. The 3-wire test is used for general ground resistance testing & the 4-wire earth resistance test is used for highest accuracy.
