PROBLEM TO BE SOLVED: To make display in a display form meeting selectively allocated parameter performable. SOLUTION: The lighting of bar graph display elements 44 consisting of display elements 44a to 44m arrayed to an arcuate form are controlled in a bar graph form, there by, the display of the level parameters can be made. The normal position of the normal parameters can be display by lighting the display elements of the normal positions. If there is a reference value exists in the parameters, any among the triangular display elements 41, 42 and 43 indicating the display elements corresponding to this reference value is lighted. When the set parameter values coincide with this reference value, the central display element 40 is lighted. |
