3.3.3 ANALOG DIAGNOSTICS
By selecting the analog submenu, the sensors con-
nected to each of the analog channels can be interro-
gated (Figure 9). The reading displayed is "raw" un-
processed data and is a decimal number ranging
from 0 - 1023 representing a voltage on the input
channel of the 10 bit ADC. Some channels have dif-
ferent scaling associated with them in hardware. The
channels are numbered and scaled as shown below:
Figure 9 — Analog Diagnostics Menu
Use the analog help button (or GenLink) to show
which user configurable channels are connected to
which sensors.
