PURPOSE:To make a setting operation unit compact by enabling plural kinds of setting by one setting operation unit. CONSTITUTION:There are provided a setting operation unit 1 which sets setting values in the range of 0.00-999 by combination of integral numbers 0-999 and multiplying factors 10 (n:O,-1,-2); a memory unit 2 which memorizes the setting values; an address assignment unit 4 which assigns the addresses in the memory unit; and a write signal generator 5 which generates signals for writing the setting values in the memory unit. This arrangement enables plural kinds of setting by one setting operation unit and makes the setting unit compact. As values of different orders can be set, standardization of lead can be made for the setting device.
