5.17 Power Standby (Instrument Shutdown)
5.17 Power Standby (Instrument Shutdown)
Pressing the power switch powers down the instrument. You are warned that
shutting down will cause the application to lose unsaved data, and the instrument
lets you respond to this warning before shutting down.
The command below has the same effect, except that you can specify Normal mode
(NORMal) or Forced mode(FORCe):
–
In NORMal mode, the system waits until you respond to the warning prompt
–
In FORCe mode, the system shuts down after 20 seconds, and all data will be
lost
If the instrument is not properly shut down prior to removal of line power, the system
will validate the Journaling File System and the Power-On Last State (if the
instrument is in Power-On Last State) during the following power-on. If a problem is
detected, a message appears indicating that the system ‘recovered’ from an
inappropriate shutdown. This is only an issue if Power-On Type is Last State. If the
Last State is not valid, the instrument will power up in the last active Mode, but will
perform "Mode Preset" on page 2207.
