NGA 2000 Reference Manual - Overview
The NGA 2000 Reference Manual provides a
detailed discussion of the inner workings of the
NGA 2000 software and its application to the
NGA 2000 Analyzers. It includes:
• Discussion of typical calibration is-
sues
• In depth discussion of network is-
sues
• Troubleshooting information
• Analyzer variable reference
This latter refers to the technical description of
the pieces of data - "variables" - available over
the LON from each of the Analyzer modules.
1-7 PLATFORM COMPONENTS
a. Operator Interface
The Front Panel Display. is a 128- by 240-pixel
liquid crystal graphics display with cold cathode
back lighting. During normal analysis operation
(Single Analyzer measurement mode), the Dis-
play indicates:
• The current concentration of the compo-
nent of interest,
• A single-line, horizontal bar graph indicat-
ing the component concentration in per-
cent of fullscale format,
• Four secondary parameters (e.g., Sample
flow), selectable from either the Analyzer
module or its associated I/O Modules.
• Current functions for the five "softkeys" lo-
cated below the display.
It may also indicate the following data for
each of up to five Analyzers in the multiple
Analyzer measurement mode (V2.3 soft-
ware, four Analyzers for V2.2):
• The current concentration of the compo-
nent of interest,
• The name of the gas measured,
• The Analyzer module TAG,
• A single-line, horizontal bar graph indicat-
ing the component concentration in per-
cent of fullscale format
