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.

4.5.9 Analog Adjust

The GC-Pro TCD Analyzer has ten 4-20 mA DC output channels

that can be assigned to the various groups. Any group can be assigned to
any output channel and it is also possible to assign groups to multiple
channels.

Channel 0 and channel 2 are unique channels. For these channels the

user can assign gain and offset values to the output. Channel 0 has an
additional feature called “WAVE” which when selected will assign the
ADC counts to the 4-20 mA output for the group assigned to channel 0.

Note: The WAVE function will not be accessible until a group has

been assigned to channel 0.

Selecting Analog Adjust from the MAIN screen brings up the

following screen.
