STARTUP AND OPERATION

Prior to initial startup, the user should perform
the leak test procedure outlined in Section 2.
For the remainder of this section, Analyzer
Module interconnection with a Platform or some
interfacing component will be assumed. Display
and Keypad information refers to that which the
user can expect to see and do with regard to the
Front Panel of the Platform.

Panel controls and indicators, see the Platform

3-2 DISPLAYS
Three kinds of Display screens are available to
the user:
• Run
Mode
• Menu
• Help
a. Run Mode Display
The Run Mode is the normal mode of op-
eration. In this mode, the Display will show
the current gas measurement, the compo-
nent of interest, the current operations of
the softkeys, and several graphics: a bar
representing the displayed concentration as
a percent of fullscale and up to four lines
showing user selectable secondary parame-
ters from either the Analyzer Module or any
IO module bound to it. See the Platform
manual for information as to how to select
these.
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 screen.
