Percent Oxygen Analyzer Introduction 1
Teledyne Analytical Instruments
3000PA-V: Gas flow through the cell block in this model is driven by
vacuum downstream from the cell block, instead of by
pressure upstream. The internal restrictor is located
downstream from the cell block to support this
configuration. All other standard features are present in this
model.
All of the above options are available in combination. For example,
the -C and -V options are combined as Model 3000PA-C-V.
1.5 Front Panel (Operator Interface)
The standard 3000PA is housed in a rugged metal case with all con-
trols and displays accessible from the front panel. See Figure 1-1. The
front panel has thirteen buttons for operating the analyzer, a digital meter,
an alphanumeric display, and a window for viewing the sample flowmeter.
Function Keys: Six touch-sensitive membrane switches are used to
change the specific function performed by the analyzer:
• Analyze Perform analysis for oxygen content of a sample gas.
