Specification of AEMC 6422 Kit-150ft - Ground Resistance Tester Kit 150ft
AEMC 6422 Kit-150ft - Ground Resistance Tester Kit 150ft
Catalog 2135.56
Ground Resistance Tester Model 6422 Kit-150ft (Digital, 3-Point) (Cat #2135.55 and Cat #2135.35)
Simple, one-button operation - eliminates errors in testing
The test button turns green when the measurement is stable
2P resistance/ 3P ground resistance measurement up to 50kΩ for highly resistive terrain
Large backlit digital display - easier to read in all lighting conditions
Automatic hold function - retains the last measurement after the reading stabilizes ensuring the measurement is valid
Automatic test frequency selection between 128 and 256 Hz, providing stable results in adverse environments
Powers up in 2 pole mode - automatically check the injector lead connection when connected to the H auxiliary rod
Convenient storage of the three measurements along with the average and % deviation - easily determines proper test results
