6. SETTING BARGRAPH
A bargraph with 20 segments divided by 10 is in the left on the display, which shows the signal level of the indicated value
(present, MAX or MIN value) against the scaled range. The bargraph range is set with the bargraph lower and upper limits.
The bargraph type can be selected among those shown in the following table.
The bargraph lower and upper limits can be set within the range of -20000 to 100000.

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.
■
SETTING RANGE OF BARGRAPH LOWER AND UPPER LIMITS
The bargraph lower and upper limits can be set within the range of -20000 to 100000. The default values are -100.00 for
the bargraph lower limit and 0100.00 for the bargraph upper limit.
IMPORTANT
• The bargraph lower and upper limits change according to changes of the display scaling values. The bargraph lower
limit is reset to the same value as the display scaling value Zero, and the upper limit is reset to the same value as the
display scaling value Span. After setting the display scaling values, the bargraph lower and upper limits can be set
arbitrarily.
• It is recommended to use the bargraph lower and upper limits within the set display scaling range.
