Current Output Setup Screens
The Current Output screens (Figure 4-20a and 4-20b) display current out-
put assignments and allows you to set up the parameters for each of the
four current outputs.
Source
Defines the analyte assigned to each analog output. Current Out
Source options include:
NONE
Select NONE if you do not wish to assign an output to a channel.
Analyte 1–8
This defines the analyte (species) of interest for the current output.
You can assign a different species for each channel. To assign an
analyte to a channel, select an analyte (species) and press
ENTER
.
Note that the species name will be displayed on the screen, not
“Analyte” (e.g., SO
2
).

Full
This is the output full-scale value, where the user enters the current
full-scale set point corresponding to 20 mA DC for the output. For ex-
ample, if Current Out 1 Full = 100 ppm, Output 1 would read 20 mA
at 100 ppm.
Zero
This is the output low-scale value, where the user enters the current
low-scale set point corresponding to 4 mA DC for the output. For
example, if Current Out 1 Zero = 0 ppm, Output 1 would read 4 mA
at 0 ppm.
