e. Measure Mode Display
The Measure Mode is the normal mode of
operation. In this mode, the Display will
show the current gas measurement, the
component of interest, the current opera-
tions of the softkeys, and several graph-
ics. A bar representing the displayed
concentration is shown as a percent of
fullscale and up to four lines showing user
selectable secondary parameters from
either the Analyzer module or any I/O
module bound to it. See the Platform
manual for information as to how to select
these. The Measure Mode display is
shown in Figure 3-5.
If more than one Analyzer module is con-
nected to the system, an additional Run
Mode display will show as many as four
(five for version 2.3 and later) gas meas-
urements on the display screen.
