Chauvin Arnoux CA6417 Earth Clamp Cat. IV

Earth clamps unlike any others...

They are particularly easy to use thanks to ergonomic innovations such as a force compensation system to keep the clamp open without any effort and an OLED display, offering visibility over an angle of 180° whatever the lighting conditions.
The automatic PRE-HOLD function when the clamp is opened and the automatic jaw calibration function at power-up help to optimize processing of the measurements provided by the clamps.

On the same screen, they offer simultaneous display of:
- the impedance and leakage current (Ω+A),
- the earth voltage,
- the breakdown of the resistive and inductive parts of the ground impedance,

They also allow users to display the impedance transposed to a frequency close to the network frequency, thus reducing measurement errors when low values are involved.

Equipped with Bluetooth communication, the C.A 6417 clamp can be used with the GTC and/or DATAVIEW® PC software to view the values in real time, recover the measurements and create standard or customized measurement reports. There is also an ANDROID application for tablets & smartphones for viewing real-time graphs, GPS geolocation of the measurements and email distribution of the measurements with graphs, comments and photos.
