to display the data in graph format. For example,
see Figures 3.32 and 3.33.

c. About Analog Display
If the data reading can be displayed as a graph
(see Figures 3.32 and 3.33), you can use the
Analog function button to display the data as an
analog gauge. Up to two gauges can be displayed
on one screen.
