Specification/Data Sheet
Amprobe Instrument Corporation Ground Resistance Tester GP-1
Rugged, battery operated, earth ground resistance tester that automatically calculates resistivity and can download to a PC
100 memory locations allow storage of two point, three point (fall of potential) and four point resistance/resistivity test results
Also functions as a voltmeter up to 600 VAC
GP-1 is a complete kit for testing existing earth ground electrodes to equipment manufacturer specifications or as mandated by national code requirements of proper grounding, typically 25 ohms or less
