Abstract

PURPOSE: To always secure the display up to the full scale with the designated number of digits by giving the monitor to the fluctuation of the partial digit signal of the input digital signal.
CONSTITUTION: Microcomputer 21 fetches the data equivalent to the number of the selected digits with every time interval Δt, and the difference to the preceding data is calculated every time. This fluctuation component is compared with reference decision values ΔVa and ΔVi. Here in case the fluctuation is large and exceeds ΔVa, the presence or absence is detected for the data in the digit higher by one than the selected digit on the data line. And in case the data exists, the displayed data part is shifted upward by one digit with no change given to the digit number. In case the fluctuation is smaller than ΔVi, the checking is given in the same way to the lower digit. And if the data exists, the data part is shifted downward by one digit. At this moment, change Δv per time Δt is detected for curve 47 on the recording paper. Based on this fluctuation, the digit is shifted smoothly to the higher rank to avoid the saw-tooth wave form.
