Claims

[Scope of utility model registration request]

In a clip-type measuring instrument equipped with a current transformer in which a pair of semicircular current transformer portions whose end surfaces are engaged with each other are each covered with an insulating material cover, each of the end surfaces of the two covers is covered with the transformer. 1. A clip-type measuring instrument characterized in that the projecting parts of the two covers project from each end face of the current transformer part and are configured so that when the current transformer parts are engaged, the projecting parts of the two covers fit into each other.
