とする交差コイル式計器。 The input measurement information is converted into first and second drive signals of a sine wave signal and a cosine wave signal according to the information, and the first and second drive signals are arranged to intersect at a predetermined angle. The movable magnet is rotationally driven by a third magnetic field that is a composite magnetic field of the first and second magnetic fields that are supplied to the first and second coils and generated from the first and second coils, respectively. In a cross-coil type instrument having a return magnet for indicating a value according to the measurement information by a pointer and returning the pointer to a zero point by a rotational operation of a magnet, a fourth magnetic field generated from the zero return magnet is provided. A cross-coil type meter, comprising magnetic field control means for generating the third magnetic field so as to include a magnetic field that cancels out the influence of the fourth magnetic field so that it does not affect the pointer when giving a measurement instruction.
