This screen has three inputs for ten peaks S00 through S09. The possible
inputs are Subtract, Add, and NA (Not Applicable). The user can assign
these inputs by touching the UP arrow button available. After touching the
ENTER button to save the inputs, a confirmation window pops up.
Note: After selecting the ENTER button there will be a delay of
few seconds to update the inputs. All other buttons (i.e.
home, cancel, back etc) available on the screen will be
disabled during the delay period.
As an example, assume Groups G00 and G01 have been setup to
monitor two different hydrocarbons with peaks associated as follows:
Group Assigned Peak
G00 S00
G01 S01
Then, it is possible to setup a group to monitor total hydrocarbon as
G03 which would have both hydrocarbon peaks assigned to it by using
the SUM function:
Group Assigned Peak
G00 S00
G01 S01
G02 S01 + S02
Similarly, group setup inputs can be provided for the other five
groups by selecting Group 5-9 icon on the first Group Setup screen.
