Filed: 1988-02-24
Abstract: PURPOSE:To derive a measured approximate value by regarding the 2nd measured values among three measured values which are detected successively as the measured approximate value when two absolute values calculated from said measured values become less than a permissible value. CONSTITUTION:When measurement is started, measured values yi are read in a data input part 2d from a measuring instrument 1 at constant intervals according to a timer 2b. A variation quantity calculation part 2e calculates the absolute value of the difference between a measured value yi which is detected this time and a measured value yi-1 which is detected last and compares the absolute value ¦Vi¦ with the preset permissible value K. When ¦Vi¦<=K, next data yi+1 is fetched to calculate the absolute value ¦Vi+1¦ of the difference between the current detected measured value yi+1 and last detected measured value yi. When ¦Vi+1<=K, the 2nd data yi among the three measurement data is regarded as the measured approximate value. Consequently, the measured approximate value is derived in a short time.
