• Product Description

    The C.A 6416 earth clamps, delivered in a carrying case, are ideal for quick earth-loop resistance measurements. 600V CAT IV, they display the earth voltage with a dangerous voltage alarm and provide additional safety during measurement.

    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.
