EXTECH 382357 Clamp on Ground Resistance Tester

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 0.03© to 1500© and True RMS AC Leakage current from 0.2mA to 30.00A. The Extech 382357 clamp-on ground resistance tester features programmable datalogging 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. The Extech 382357 clamp-on ground resistance tester ships complete with 9V battery, resistance check plate, and durable metal storage case. Applications for the Extech 382357 Clamp-On Ground Resistance Tester Verify resistance of cellular and communication tower ground grids Check utility transmission systems and grounding rods Maintenance on electric transportation systems Ideal for grounding systems in sub-stations, factories and office buildings Features: Ground resistance measurements down to 0.03© with 0.002© maximum resolution True RMS AC leakage current range of 0.2mA to 30A with 1.000mA max resolution Programmable datalogging with 116 data points Programmable Hi/ Lo alarm 0.9 " jaw size for large ground rods Automatic self calibration when powered on 9999 count high contrast LCD display Included resistance checkplate confirms meter accuracy Electrical noise detection feature prevents inaccurate readings Data hold and continuity beeper
