A clamp unlike any other Ergonomics The rugged C.A 6416 and C.A 6417 clamps are designed for day-to-day use. Their weight has been limited by using highperformance magnetic materials. To ensure more comfortable use, the clamp’s jaw benefits from a new feature: a force compensation system installed on the trigger. Minimal effort is required to keep the clamp open in order to optimize handling of the product while reducing user fatigue. As an additional safety feature, a protective guard prevents the hand slipping during measurements. The moulded-silicone rotary switch is easy to operate even...

... An exceptional display! The C.A 6416 and C.A 6417 clamps benefit from a top-quality display based on OLED technology, which offers better contrast, a sharper image and better colour rendering. With its 180° viewing angle, it is easy to read in all circumstances. There are two display modes available: • Standard mode to display a single screen with measurement results • Advanced mode to display 3 separate screens: - Measurement result - Ground voltage - Resistance and loop inductance values Standard mode: Impedance and leakage current Screen 1: Impedance and leakage current Screen 2:...

Operation The C.A 6416 and C.A 6417 clamps are simple to use and are designed to measure the loop impedance in a parallel ground network. Classic method The diagram illustrates the general case involving measurement of a loop resistance comprising: • The ground connection Rx; • The ground; • Several ground connections with a resistance Ri; • protective ground wire looping all these grounds A together, contributing an inductive component. The clamp includes two functions grouped in the measurement head: • he clamp’s generator winding applies an AC voltage with a constant level E. T • The...

Applications Ground measurements in urban areas are often difficult because it is not possible to set up ground stakes. These ground clamps can be used to perform selective measurements on a parallel ground system without disconnecting conductors or even setting up stakes. In the case of regularly-spaced ground connections or an underground ground loop, the use of ground clamps to measure low values allows you to check the continuity of the loop conductor tested. Measurement of grounds in parallel on MV/LV installations To ensure the quality of the ground present on the whole distribution...
