The Extech 382357 clamp-on ground resistance tester allows the user to measure ground resistance without the use of auxiliary ground rods. The Extech 382357 clamp-on ground resistance tester measures resistance from 0.03Ω to 1500Ω and True RMS AC Leakage current from 0.2mA to 30.00A. The Extech 382357 clamp-on ground resistance tester features programmable data logging with 116 points, programmable hi/lo alarms, 0.9″ jaw size, self-calibration when powered on, and verification resistors to confirm the accuracy of the meter.
