Setting the Instrument Power Mode
Use the three power mode icons in the Tune window (Figure 59) to set the MS’s power mode
(on, standby, or off ).
When you remove the API source housing or the spray insert, the MS automatically switches
to off mode.
In standby mode, the System LED on the front panel turns yellow and the MS turns off the
electron multipliers, conversion dynodes, 8 kV power to the API source, main RF voltage,
and ion optic RF voltages. The auxiliary, sheath, and sweep gas flows remain on and return to
their standby default settings (2 arbitrary). See Chapter 8, “Using the MS Power Options.”
