Ground, earth electrode and coupling measurement using traditional rod methods 3 testers in one: resistivity, earth, coupling Validation of measurement through automatic check: 3 lights indicate the presence of faults liable to impair measurement results Heavy-duty on-site case with cover for use on difficult grounds Large LCD display with backlighting Earth and Resistivity Testers

obust and watertight, the C.A 6460 and C.A 6462 are easy-to-use instruments designed specially for use in the field. Wherever you need to install an electric ground connection or certify an existing one, the C.A 6460 and C.A 6462 help you perform accurate, reliable and quick diagnosis while providing the friendliest and safest test environment. COMPLETE AND WELL-DESIGNED TOOLS Using the conventional rod-based method, the C.A 6460 and C.A 6462 measure resistivity ("4-wire" connections), ground resistances ("3-wire" connections) and coupling between electrically independent earth electrodes ("4-wire"...

USE / APPLICATIONS: Ground resistivity measurement with the "Wenner method" (4-rod method) Depending on the soil's properties, this measurement defines the best positions, depth and geometry necessary for installing electric ground connections. Ground connection resistance measurement with the "TAGG method" (62 % method) This method, using 2 auxiliary rods, measures up to 2000 Ω, even in worst-case conditions. Ground connection to be measured S(Y) Coupling measurement between two earths 4-wire measurements are considered better than 2-wire because they free you from cord resistance, which is...
