作手段とから構成される指示計器。 A shaping means that inputs a pulse signal with a frequency corresponding to the measured quantity and shapes the pulse signal, and an ammeter that uses the output signal of the shaping means to indicate the measured quantity correspondingly to the scale on the dial and the rotating pointer. An indicating instrument comprising: a scale portion having a full display width from the 0 scale to the MAX scale for the entire indicated range to be measured and displayed; dial plates arranged side by side as enlarged display parts having intervals larger than the interval between scales in width; a determination means for determining a predetermined measurement value corresponding to the intermediate scale based on the pulse signal; and a determination output of the determination means. a switching means for switching the output characteristic of the shaping means from a first characteristic corresponding to the entire display width to a second characteristic corresponding to the enlarged display section; and validating or invalidating a determination signal from the determining means to the switching means. An indicating instrument consisting of a manual operating means for controlling the
