SECTION 3

OPERATION

3-1 OVERVIEW

Prior to initial startup, the user should perform the leak test procedure outlined in Section 2- 4c on page 2-3.

For the remainder of this section Analyzer Module interconnection with a Platform or some interfacing component will be assumed. Display and keypad information shall refer 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 the Platform front panel controls and indicators, see the Platform instruction manual, Displays & Operating Keys.

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 (see Figure 3-1 on page 3-3) will show current gas measurement, the component of in- terest, the current operations of the soft- keys, and a graphic bar representing the displayed concentration as ppm or as a percent of oxygen.

If more than one Analyzer Module is connected to the system, the Run Mode display will show as many as four gas measurements on screen. Alarm messages may also appear on the display (See Table 3-1 on page 3-2).

b.Menu Displays

The menu structure enables the user to access data and functions, and put infor- mation onto the network.

The Main Menu (Figure 3-2 on page 3-3) is subdivided into three levels of control based generally on which personnel is likely to use it: Basic Controls, Expert Controls and Setup, and Technical Level Configuration. See Figure 3-3 on page 3- 3, Figure 3-4 on page 3-4, and Figure 3-5 on page 3-4. Many layers of the menu structure are described at appropriate places throughout this manual.

From the Run Mode display, press the MENU softkey to enter the Main Menu (Figure 3-2 on page 3-3).

c.Help Displays

The Help structure is intended to be an on-line "tutorial," context sensitive and topic-interconnected, so that the user can practically operate NGA2000 without need of an instruction manual (Figure 3-6 on page 3-4).
