Even in tight spaces, you can handle this current clamp adapter with ease! The movable clamp arm can be fully retracted, allowing you to grasp tightly positioned cables in control cabinets as if with a hook. With the current clamp adapter for non-contact current measurement, you can measure both AC and DC currents up to 400 A. You can connect the current clamp adapter to a suitable digital multimeter from Testo or to digital multimeters from other brands that resolve in the mV range.
