(1) Analysis value data (fi xed to 45 characters)
The data is output only when Execution is set to “Executed” and Output fl ag is set to “Provided”
on the Peak Setup-Specifi c screen.
The packets for the processes are classifi ed as follows:

Program output No output
● Type A
If a unit other than ppm or % or no unit is used, data is not output.

a: Stream number (01 to 31)
b: Peak number (01 to 99) *Relative peak number
To address all 255 peak numbers, S comes in the second digit (from the head) for the peak numbers 01 to 99, 1 for the numbers
100 to 199, and 2 for the numbers 200 to 255.
c: Analysis value (5 digits)
The data format for analysis values depends on the measurement range for the peak setting (see Table 11).
Analysis values are rounded.
Table 11 Data format for analysis values
Output value Measurement range Remarks
n.nnn 0.001 to 9.999 9.999 is used for all values of 9.9995 or more.
nn.nn 10.000 to 99.999 99.99 is used for all values of 99.995 or more.
nnn.n 100.000 to 999.999 999.9 is used for all values of 999.95 or more.
nnnnn 1000.000 to 9999.999 99999 is used for all values of 99999.5 or more.
n: any value from 0 to 9.
d: Unit (PPM, %)
e: Concentration error alarm (A:CHL = Higher limit, A:CLL = Lower limit)
They will be dummy spaces if no error occurs.
f: Retention time (0000.0 to 9999.9)
The unit is in seconds. The position of the decimal point is fi xed. 0000.0 is used for values of 0 or less and 9999.9 for those of
9999.9 or more.
g: Retention time error alarm (A:RT)
They will be dummy spaces if no error occurs.
h: Analyzer number (1 to 240) (zero suppression provided)
<GC6>
The Analyzer number (h) to be used in the <GC1000/GC8> format is not provided. Only S comes
in the second digit from the head because the peak numbers are 01 to 99.
