CONSTITUTION: A hook meter apparatus (100) comprises a body part (110) and a hook part (150). The body part has a circuit to measure the current of wires using electromotive force induced by the wires. The hook part covers the wires to induce the electromotive force from the wires. The hook part comprises a wide hook part (160) and a narrow hook part (170). The wide hook part comprises a first wide hook member (161) and a second wide hook member (165). The wires are inserted in the wide hook part to form a first insertion part. The width of the narrow hook part is narrower than the first insertion part. |
