Spesifikasi Ground Resistance Tester (Digital 3-Point) AEMC 6424
AEMC 6424 - Ground Resistance Tester (Digital, 3-Point)
Catalog 2135.57
Ground Resistance Tester Model 6424 (Digital, 3-Point)
Ground Resistance Tester Model 6424 (Digital, 3-Point)
Simple, one-button operation - eliminates errors in testing
The test button turns green when a 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 checks 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
The Digital Ground Resistance Tester Model 6424 performs 2-pole and 3-pole ground resistance measurement. This direct reading tester is auto-ranging, so it automatically seeks out the optimum measurement range. The Model 6424 is easy to use - simply connect the leads, press to measure, and read. The large LCD also indicates low battery status, over range, and lead reversals.
