AEMC 6424
Catalog #: 2135.57
Digital, 3-Point Ground Resistance Tester, AC/DC Voltage and AC Leakage Current
- Overview
- Specifications
- Summary
Product Highlights
- Checks AC/DC voltage and AC leakage current
- Stores 52, 62 and 72% measurements - eliminates errors in determining the ground resistance
- Leakage current measurement from 0.5mA to 70A
- Battery recharging via AC adapter, USB or vehicle DC port b
- Simple, one button operation - eliminates errors in testing
- Test button turns green when measurement is stable
- 2P resistance/ 3P ground resistance measurement up to 50kΩ for highly resistive terrain
- Large back lit digital display - easier to read in all lighting conditions
- Automatic hold function - retains last measurement after the reading stabilizes
- Automatic test frequency selection between 128 and 256 Hz
- 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
- Built in test lead compensation capability
- CAT IV 600V rated for a high level of operator safety
- Color coded leads and terminals provide fast, error-free connection hook-up
- Detects and prohibits hazardous voltage measurement
- Direct access to all functions, even when wearing work gloves
- Rugged water resistance case, for all terrain use
- Built-in display stand to prop up instrument for seeing the display better when placed on the ground
