3.18.4 ANALOG DIAGNOSTICS

By selecting the analog submenu you can test the sensors con-
nected to each of the analog channels (Figure 3.27). The reading
that is displayed is "raw" unprocessed data and is a 10 bit number
ranging from 0 - 1023 representing a voltage on the input chan-
nel. Some channels have different scaling associated with them
in hardware. The channels are numbered and scaled as shown
below.

You can use the analog help button to show you how the user con-
figurable channels are connected to which sensors (Figure 3.28).
