Instrument with crossed-coil type movable magnet.

摘要

An instrument has a crossed-coil-type movable magnet in which a movable magnet rotatable about the shaft of a pointer needle is installed in a crossed coil unit and a measured quantity or the like is operated by supplying electric power to the crossed coil unit. The instrument includes an input unit to receive an input from a measurement object to be measured, an arithmetic section or ROM to set directions and time values for supplying electric current to the coils of the crossed coil unit, and a circuit section to deliver pulse signals with predetermined potential values to the crossed coils under conditions associated with the directions and time values, to provide a very broad angular range of the pointer needle.
