The clamp meter supports you in the exact recording of current strength and uses the magnetic field that surrounds the conductor for its indirect measurement of the magnetic field. It is therefore not necessary to disconnect the electric circuit to activate the measuring instrument directly on the cable, because the measurement is contactless.
