Chart F - Battery Voltage
Use this chart to convert the average value of the last two analog-to-
digital readings into the battery voltage at time of snapshot. Take the
value from field FFF on Snapshotscreen-b.
Analog-to-Digital
Value
Voltage
186 11.1
188 11.2
190 11.3
191 11.4
193 11.5
195 11.6
197 11.7
199 11.8
200 11.9
202 12.0
204 12.1
205 12.2
Analog-to-digital values that fall between those listed in the table
may be interpolated to determine the voltage.
For example, the example snapshot screen-b shows the value as
decimal 194, so the voltage value is 11.55.
Chart G - Pumping pressure
Use this section to interpret field GGG on snapshot screen-b for all
system state codes except 33, 35 or 93 which are described later in
this chapter. This example shows field GGG with a value of 131.
These instructions explain how to compute the pumping pressure of
the pump at the time of the snapshot.
The pressure sensor has a zero offset Analog-to-Digital value of 0 to 3.
In addition to that, every increment of 21 represents 1 psi.
Use the following steps to compute the pumping pressure contained
in field GGG on Snapshot-b:
1. Take the decimal value in GGG and subtract 5.
2. Divide the result by 21 to give the pressure in psi.
These steps can be represented by the formula:
(GGG-5) / 21 = n psi
As an example of how the formula works:
If the value of GGG is 131: (131-5) / 21 = 6 psi
