Deskripsi produk
Ground Resistance Tester Model 6424 (Digital, 3-Point)
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, overrange, and lead reversals.

The 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).
