AEMC 2135.59 Ground Resistance Tester Model 6424 Kit-300ft (Digital, 3-Point) (Cat #2135.57 & 2135.36)

The AEMC 2135.59 is a digital ground resistance tester kit built around the manufacturer Model 6424. It performs 3-pole ground resistance, 2-pole resistance, AC/DC voltage, and AC current measurement with MN72 probe support. The auto-ranging, direct-reading design supports electrical grounding checks with clear LCD measurement feedback.

- 3P mode measures ground resistance through H, S, and E terminal connections to produce direct resistance readings.
- 2P mode measures resistance across the test connection for simplified resistance checks.
- Auto-ranging operation seeks the optimum measurement range before displaying the result.
- One-shot or continuous measurement modes support single readings or repeated measurement activity.
- Stored 52%, 62%, and 72% 3P resistance readings support average and percent deviation calculation.

- AC/DC voltage measurement range: 0.1 to 600 V.
- AC current measurement range: 0.5 to 60.00 A with MN72 probe.
- 2P ground resistance measurement range: 0.05 Ω to 50.00 kΩ.
- 3P ground resistance measurement range: 0.50 Ω to 50.000 kΩ.
- Measurement frequency: 128 Hz or 256 Hz, automatically selected.

- Ground resistance testing for grounding systems.
- 2-pole resistance measurement.
- AC/DC voltage and AC current measurement.
