うにしたことを特徴とするクリップオン電流計。In the clip-on ammeter, a conductor through which a current to be measured is flowing is sandwiched between two cores made of high magnetic permeability magnetic material, and the current to be measured is detected by detecting the magnetic flux density in a gap provided in a part of the cores. Another gap is provided in a part of the core, and a magnetic metal member that can be inserted into the gap and has the same magnetic permeability as the core is prepared, and the magnetic metal member is inserted into the gap depending on the magnitude of the measurement current. A clip-on ammeter characterized in that it can be inserted into or removed from the.
