BENNING CM 9-1
The BENNING CM 9-1 is a leakage current clamp meter for measuring leakage currents and differential currents in electrical installations and equipment. It is designed for tasks where very small currents need to be measured precisely, without interrupting the circuit. It is therefore relevant for troubleshooting, inspection, and maintenance of installations according to VDE 0100/0105 as well as EN 50678 and EN 50699.
The most important point is that it combines sensitive leakage current measurement with the normal multimeter functions often needed in the same work situation. It measures up to 60 A AC, AC/DC voltage up to 600 V, resistance up to 600 kΩ, and has continuity testing. This makes it practical when you want to check a fault current and quickly follow up with other electrical measurements.
In the 6 mA range, it has a resolution down to 1 µA, so small changes in leakage current can be clearly seen. The built-in low-pass filter function from 40 Hz–70 Hz helps with measurements where you want to focus on lower frequencies. In addition, it has HOLD and peak value storage, so a measurement can be held or saved when necessary.
The jaw opening is 23 mm, and the instrument is classified CAT IV 300 V and CAT III 600 V.
