<Appendix D Action of External Input and Output Signals>
App.D-2
IM 11B08A01-01E
Holds the stream identifi cation signal of the latest measured stream other than calibration or
validation.
Actions of analog output and contact output are described in (2) through (4) below. For actions of
contact output other than stream identifi cation signals, see the Contact Output.
 When Actual Stream is Set for Output Stream Number (without 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 1). Specify the GCM number, output
stream number, peak number, and the upper and lower limits of the partial range for the peak of
which analysis results are to be output.
When an actual stream number is set for the output stream number, up to 2 analysis values of
different streams are output.
Set the stream identifi cation signal output to “None” for each GCM (Figure 2).
