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.
