PURPOSE:To set simply a probe to a conductor and at the same time to eliminate the subsequent correction of the conductor by forming through hole to a board for the insertion of the probe. CONSTITUTION:Plural through holes 14 are drilled to the board 12 at both sides of the prescribed conductors 13 respectively. These holes 14 are formed rectangular for the insertion of a probe 10 of an ammeter and arrayed in a row close to each conductor 13 so that one of the holes 14 at both ends of adjacent conductors 13 can be shared by these adjacent conductors when the probe 10 is inserted. Thus, it is possible to insert the probe 10 into the holes 14 at both sides of the conductor 13 respectively and to enclose annularly the conductor 13, i.e., a subject of measurement by the probe 10.
