PRODUCT OVERVIEWThe Chauvin Arnoux CA6470N TERCA 3 is a comprehensive and accurate multifunction earth and resistivity tester, designed for professionals who need to perform advanced diagnostics on electrical earthing systems. Unlike simpler testers, the CA6470N offers multiple testing methods and expert-level calculation functions. |
KEY FEATURESHigh precision: The 4-pole method provides up to ten times greater accuracy for measuring very low earth resistances, making it suitable for requirements from power distribution and transmission companies.Advanced diagnostics: The tester conducts a self-diagnosis before each measurement to detect any faults that could cause errors, such as poor connections or signal interference. Variable test frequency: For earth and earth resistance measurements, the test frequency is adjustable from 41 Hz to 512 Hz, which helps to avoid interference and improve measurement quality. Robust and portable design: The device is built in a compact, rugged, and leakproof (IP53) enclosure, with color-coded terminals for easy and error-free connections. Data storage and export: It can store up to 512 test results in its internal memory. An optically-isolated USB port allows for data transfer to a PC for analysis using the included "Ground Tester Transfer" software. Rechargeable battery: A NiMH rechargeable battery powers the device and can be charged via a mains adapter or a vehicle cigarette lighter.
