Chauvin Arnoux CA6470N TERCA 3 Earth & Resistance Tester

Description

The Chauvin Arnoux CA6470N TERCA 3 is a comprehensive and multi-function earth and resistivity tester. It is a rugged and portable device that offers high accuracy for professionals performing diagnostics on electrical earthing systems. The CA6470N features multiple testing methods, variable test frequencies, and data storage capabilities.

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.
