AEMC 2135.56 Ground Resistance Tester with 2P and 3P Modes

The AEMC Model 6422 is a digital ground resistance tester for resistance and 3-pole ground resistance measurements. It performs direct-reading ground testing with automatic range selection across supported 2P and 3P modes. The 150 ft kit configuration supports field-based earth ground testing workflows.

- Lead connection and test initiation produce a direct resistance reading on the LCD.
- Auto-ranging operation seeks the optimum measurement range for the connected test condition.
- One-shot measurement supports single test capture, while continuous mode supports repeated readings.
- Low battery and overrange indications help identify measurement status during use.

- 2P ground resistance mode covers 0.05 Ω to 50.00 kΩ.
- 3P ground resistance mode covers 0.50 Ω to 2.000 kΩ.
- Measurement frequency is automatically selected at 128 Hz or 256 Hz.
- No-load voltage is ±10 V peak, with maximum test current of 20 mA.
- Backlit LCD display supports direct reading of resistance values.

- Ground tester use for earth ground resistance checks.
- Ground rod tester use for 3-pole grounding measurements.
- Ground continuity and ground wire testing workflows supported by resistance measurement mode.
