6424 Ground Resistance Tester Digital, 3-Point

6424 Ground Resistance Tester

The Digital Ground Resistance Tester Model 6424 performs resistance and 3-pole ground resistance measurements. 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 and overrange.

Model 6424 comes with 3 safety color-coded terminals to aid in easy hookup, measure voltage up to 600V AC/DC and AC current up to 60A with the optional current probe Model MN72.

The Model 6424 is powered by 6 x AA rechargeable NIMH batteries. The Ground Resistance Tester Model 6424 is also available in complete Kits (150ft and 300ft).

• Simple, one button operation - eliminates errors in testing
• Test button turns green when measurement is stable
• 2 P resistance measurement up to 50 kΩ
• 3 P ground resistance measurement up to 50 kΩ (Model 6424) 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 ensuring the measurement is valid
• Automatic test frequency selection between 128 Hz and 256 Hz, providing stable results in adverse environments
