IMPORTANT
• The bidirectional bar shows deviation in both directions from the middle point between the lower and upper limits.
• The number of the LED segments is 20 divided by 10. The bar increases or decreases by 2 segments.
• In setting ‘bargraph upper limit < bargraph lower limit’, the bargraph image is upside down of the above ones.
