摘要 PURPOSE:To easily correct an input numeric value even if a numeric value which cannot be set is input by providing means for displaying input data having error on a display unit, and upward and downward correction keys for correcting input data value in increasing and decreasing directions. CONSTITUTION:When data which does not satisfy a condition as a set value is input, a set malfunction lamp is lit. Here, in order to correct the error input data, a key 1 of an upward correction key or a key 2 of a downward correction key is depressed. Further, relative relation between the maximum value amax and the minimum value amin of the data value already erroneously input is checked, and if the erroneous input data value falls within a range between the values amax and amin, it is corrected to a set value which can be set immediately above the erroneously input data value.
