When “99” is Set for Output Stream Number (with Stream Identifi cation Signal)

Select Normal output for the AO chromatogram on the A/O setting screen to open the analog

hold output (analysis result output) setting screen (Figure 5.37).
To output an analysis value for all the streams that belong to the GCM, specify the GCM number

and set the output stream number to “99.” Next, specify the peak number as well as the upper

and lower limits of the partial range. The #2 output peak setting is invalid.

When “99” is specifi ed for the stream number, be sure to use contact output as a stream

identifi cation signal.
For an example of settings in the case where a stream identifi cation signal is used, see 6.1.3.
