Putting the Instrument in Shutdown Mode

Except in emergency situations, you should put the Agilent 7500 into the Shutdown
mode before turning off the main power.
To return the instrument to Shutdown mode, complete the following steps:
Follow the instructions in "Putting the Instrument in Standby Mode"
When the instrument is changing to Shutdown mode, argon gas is introduced into
the vacuum chamber. For this reason, the argon gas supply needs to be opened until
the instrument has switched to Shutdown mode.
The dialog box appears.
The instrument starts to go to the Shutdown mode. After a short time, argon gas is
introduced into the vacuum chamber. This is done to prevent pump oil from going
up into the vacuum chamber. The turbo and rotary pumps are turned off. Only the
main power to the instrument remains on. The title bar of the instrument control task
shows that the instrument changes to Shutdown mode.
If argon gas is not supplied, air will be introduced into the vacuum chamber instead
of argon. In this case, it may take more time to go back to the Standby mode.
