STARTUP  AND  OPERATION 
3-1 OVERVIEW 
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. 
(For a complete description of Platform Front 
Panel controls and indicators, see the Platform 
instruction manual. 
3-2 DISPLAYS 
Three kinds of Display screens are available to 
the user: 
• Run

• 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.
