12.2.7 Split ratio program
You can change the split ratio during a split analysis. In addition, you can set a split ratio
program after the sampling time has elapsed during splitless analysis.
The split ratio program and the gas saver perform basically the same operation. However,
the split ratio program is used for more general purposes.
12.2.7.1 Screen description
Select [Split Prog] (PF menu) from the [FLOW] key main screen when not in “DIRECT”
mode to display the Split Ratio screen shown in Fig. 12.2.12.
12.2.7.2 Parameter list
TIME
Range: 0.00−9999.99 min, Default: 0.00 min
Set this parameter to display the split ratio used previously in the Split Ratio column.
SPLIT RATIO
Range: -1.0/0.0−9999.9, Default: -1.0
Set the split ratio.
If the split ratio is set to “-1.0”, the total flow rate remains constant regardless of the
oven temperature.
