Measure currents up to 400 A AC or 400 A DC non-contact with your digital multimeter, without having to disconnect the circuit. Simply connect the current clamp adapter to a multimeter, oscilloscope, or similar device using the 4 mm banana plugs. The output of the current clamp adapter is in mV/A. The device is very robust due to its soft rubber protection and is additionally equipped with a non-contact voltage tester.
