5975 Series MSD Operation Manual 51
Operating the MSD from the Data System
The software performs tasks such as pumping down, monitoring pressures,
setting temperatures, tuning, and preparing to vent. These tasks are described
in this chapter. Data acquisition and data analysis are described in the
manuals and online help supplied with the MSD ChemStation software.
Operating the MSD from the LCP
The local control panel (LCP) shows the status of the MSD or initiates a task
on the MSD without using the Agilent GC/MSD ChemStation.
The GC/MSD ChemStation may be located anywhere on the site local area
network (LAN), so the GC/MSD ChemStation might not be near the
instrument itself. And because the LCP communicates with the GC/MSD
ChemStation via the LAN, you can access GC/MSD ChemStation software
functions, such as tuning and starting a run, right from the MSD.
Modes of operation
The LCP has two modes of operation: Status and Menu.
Status mode requires no interaction and simply displays the current status of
the MSD instrument or its various communication connections. If you select
[Menu], then [No/Cancel], you will be returned to the Status mode.
Menu mode allows you to query various aspects of the GC/MSD and to initiate
some actions like running a method or sequence or preparing to vent the
system.
To access a particular menu option:
NOTE
Only certain functions are available from the LCP; the GC/MSD ChemStation is the
full-featured controller for most instrument control operations.
Press [Menu] until the desired menu appears.
Press [Item] until the desired menu item appears.
