AEMC 2135.58 Ground Resistance Tester Model 6424 Kit-150ft (Digital, 3-Point) (Cat #2135.57 & 2135.35)
Model Number: AEM213558
The Digital Ground Resistance Tester Model 6424 performs 3-pole ground resistance, 2-pole resistance, AC voltage and current (accessory MN72 probe needed) 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 600 V AC/DC and AC current up to 60 A with the optional current probe Model MN72.
The Model 6424 is powered by (6) 1.2 V AA NIMH rechargeable batteries. The Ground Resistance Tester Model 6424 is also available in complete Kits (150 ft and 300 ft).
