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

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).

FEATURES
• 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 2 kΩ (Model 6422)
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 and 256) Hz,
providing stable results in adverse environments
• 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 – easily determines
proper test results
• Built-in test lead compensation capability – improves the
accuracy of low resistance measurements
• 600 V CAT IV rated for a high level of operator safety
• Checks AC/DC voltage (Model 6424)
• Stores (52, 62 and 72) % measurements – eliminates
errors in determining the ground resistance (Model 6424)
• Leakage current measurement from 0.5 mA to 60 A (Model 6424)
• Battery recharging via AC adapter, USB or vehicle DC port
(Model 6424)
• Color-coded leads and terminals provide fast,
error-free connection
• Detects the presence of hazardous voltage and
prohibits 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
