Basic remote control concepts
The GUI and the remote control command set both aim at maximum operating conven-
ience. In manual control this generally means that the control elements are easy to find
and intuitive to handle, and that the effect of each operation is easy to verify on the
screen. Convenient remote control operation depends on a simple and systematic pro-
gram syntax and on a predictable instrument state; the display of results is secondary.
These differences suggest the peculiarities in the analyzer's remote control concept
discussed in the following sections.

Traces, channels, and diagram areas
Like in manual control, traces can be assigned to a channel and displayed in diagram
areas (see section Traces, Channels and Diagram Areas in Chapter 3). There are two
main differences between manual and remote control:
●
A trace can be created without being displayed on the screen.
●
A channel must not necessarily contain a trace. Channel and trace configurations
are independent of each other.
The following frequently used commands create and delete traces, channels, and dia-
gram areas:
