With its ability to measure alternating and direct current, the F67 AC+DC TRMS leakage current clamp meter addresses issues caused by new energy sources as well as changes in the currents consumed by equipment and installations.

In the event of an insulation fault or untimely tripping of a differential protection system, the F67 clamp is the ideal tool for detecting and measuring, under voltage, earth leakage currents on installations powered by alternating current as well as those using a direct current power source.

In the context of maintenance and optimal energy expenditure management, the F67 clamp's ability to measure very small DC and AC currents allows you to measure and control standby or idle currents, control signals, etc.

The design of its jaw allows the measurement of the weakest currents with great precision.

Compliance with the IEC 61557-13 standard, Class 1 ≤ 100 A/m, the most demanding criterion, guarantees immunity to external electromagnetic fields and interference and parasitic signals at an unprecedented level. This ensures that the position of the conductors in its jaw has little influence, which is particularly important when measuring differential currents.

Another new feature of the F67 model is the patented RC3 (RC-Cube) function that analyses the residual leakage currents seen by the differential protection and informs the user if it is no longer suitable.

Versatile for everyday use, the F67 model is also a clamp meter that measures voltages, resistances, etc.
