INET operation
In using the INET function, chromatographic parameters are entered
normally through the HP 5890 keyboard. Integration parameters are
entered at the controller. Parameters for other devices on the INET loop
may be entered at the controller, or at their own keyboards. Collectively,
the separate sets of parameters constitute a single set of parameters for
an analysis.
The intent here is to discuss INET operation only from the point of view
of the HP 5890. For specific information regarding INET loop control
(configuration, workfile storage and recall, etc), consult the appropriate
operation manuals for the INET controller device. Also consult
appropriate manual(s) for other devices (sampler/event control module,
etc) configured in the loop.
Typical displays occurring when the HP 5890 is under INET control are
shown in Figure 5•7.
