NOTE:
The Bar Graph is an optional
hardware feature that is
recommended for all setpoint
applications. Any of the IQ plus
800/810 models can be fitted
with the Bar Graph. It mounts
on the front side of the display
board as shown in Figure 8-4.

Another popular use for the bar graph in "GRAPH" mode is as an "over/
under" indicator. In this application the low level is set at one end of a band
width and the high level is set at the other end. The difference between the
low and high points becomes the "accept" band. When the weight on the
scale is below the accept band, all segments of the bar graph (except the last
segment on the left) are dark. When the weight reaches the low level point,
the bar graph segments begin to light from left to right. When the weight is
halfway between the high and low points, all of the bar graph segments will
be lit. As the weight increases from this point the segments will begin to turn
OFF from left to right. When the weight exceeds the high point of the band,
all of the segments will be turned OFF, except the last one on the right. This
segment remains ON to show that the upper range of the band has been
exceeded.
The bar graph can also be configured to display a particular load cell
channel. For example, the weight value of scale 1 can be displayed digitally,
while the weight value of scale 2 can be displayed graphically on the bar
graph.
