ことがある。そして。[Problem to be Solved] However, in the conventional crossed coil type instrument, the above-mentioned zero return magnet is simply inserted in the surplus space. Therefore, when a crossed coil type meter is attached to a moving object such as an automobile, the zero return magnet may move back and forth and left and right within the case. and.
このように帰零用磁石が動くと、計器の指針はその帰零
位置が異なり、正確な指示がなされない。If the zero return magnet moves in this manner, the zero return position of the pointer of the instrument will be different, and accurate instructions will not be given.
