Figure 1-1 is an illustration of the front of the Model 3000PB Oxygen
Analyzer with the outer door open showing the control panel (which is also
the inner door).
All displays on the standard 3000PB are visible from outside the hous-
ing. The instrument has a digital meter and an alphanumeric display, which
are viewed through a glass viewing window in the outer door of the main
housing, and a sample flowmeter on the gas control panel attached to the
main housing. They give the operator constant feedback from the instrument.
The operator controls are pushbutton membrane switches located
behind the outer door of the housing. All of them are reached by unlatching
and swinging open the outer door of the enclosure. They are described
briefly here and in greater detail in chapter 4, Operation.
Figure 1-2 shows the 3000PB with the outer door and inner door both
open. The inner door is opened for access to the electrical connections and to
the cell block which houses the Micro-Fuel Cell. Door-mounted components
are shown in chapter 5, Maintenance.
