ABSTRACT:
A meter device includes an indicator unit, movably supported within a predetermined range, for representing an amplitude value of an input signal by a movement amount Δθ from a reference position θ0which is one end of the predetermined range. A gain acquiring unit acquire a gain of the input signal; and a maximum movement amount determining part determines a maximum movement amount ΔθM of the indicator unit at the gain based on the gain acquired by the gain acquiring unit. A drive control unit moves the indicator unit to a position corresponding to the amplitude value of the input signal between the reference position θ0and a maximum movement position θM moved from the reference position θ0by the maximum movement amount ΔθM based on the maximum movement amount ΔθM determined by the maximum movement amount determining part and the amplitude value of the input signal.
