Key Features- Measurement functions: This tester is a "4-in-1" device capable of performing earth resistance, earth coupling, soil resistivity, and continuity/resistance measurements.
- Earth measurement methods: The CA6470N supports both 3-pole and 4-pole earth measurements using the traditional rod methods. The 4-pole method offers higher accuracy, especially for measuring very low earth resistance values.
- Selective 4-pole measurement: This method can be performed with an optional clamp-on ammeter to avoid the need to disconnect the earth resistance for measurement, which saves time.
- Soil resistivity: The device uses the Wenner and Schlumberger methods for soil resistivity testing and automatically calculates the results.
- Variable test frequency: The test frequency can be adjusted between 41 Hz and 512 Hz, which helps to avoid interference from parasitic signals and improve the quality of measurements.
- Advanced diagnostics: The unit performs a self-diagnosis before each test to detect potential faults or poor connections that could cause errors.
- Ergonomic and rugged design: Built in a watertight IP53-rated enclosure, the tester is suitable for fieldwork. It also features a large, backlit LCD screen and color-coded terminals to simplify connections.
- Data storage: The CA6470N can store up to 512 test results in its internal memory.
- Connectivity: Data can be transferred to a computer for processing via an optical/USB link using the included Ground Tester Transfer (GTT) software.
- Rechargeable battery: The device is powered by a rechargeable NiMH battery and comes with an external charger that can be used with a mains outlet or vehicle cigarette lighter.
