To do an autotune
Tuning the multimode source is done in MM-APCI mode only. Autotune is
performed from the same menu as with all sources.
• From the MSD Tune view, select Instrument > Autotune menu item.
The tune report will have a header with either the title MM-APCI Positive
Mode - Standard Scan or MM-APCI Negative Mode - Standard Scan. You can
run the check tune after autotuning to validate that the instrument is passing
check tune criteria. Do the autotuning after the system has had at least 8
hours to equilibrate vacuum and temperatures.
