AEMC Ground Resistance Tester Model 6424 (Digital, 3-Point)

AEMC 6424 Description:

The AEMC 6424 Digital Ground Resistance Tester 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, overrange, and lead reversals.

The 6424 (2135.57) comes with 3 safety color coded terminals to aid in easy hookup, measure voltage up to 700V AC/DC and AC current up to 70A with the optional current probe Model MN72.

Key Features:

• Checks AC/DC voltage and AC leakage current
• Stores 52, 62 and 72% measurements - eliminates errors in determining 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 50k? for highly resistive terrain
• Large back lit digital display - easier to read in all lighting conditions
• Automatic hold function - retains last measurement after reading stabilizes
• Automatic test frequency selection between 128 and 256 Hz
• Powers up in 2 pole mode - automatically checks injector lead connection when connected to H auxiliary rod
• Convenient storage of three measurements along with average and % deviation
• Built in test lead compensation capability
• CAT IV 600V rated for 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 display better when placed on ground
