Figure 1-1 is an illustration of the front of the Model 3000TB
­XL Oxygen
Analyzer with the outer door open showing the control panel (which is also
the inner door).
All displays on the standard 3000TB
­XL are visible from outside the
housing. The instrument has a digital meter and an alphanumeric display,
which are viewed through a glass viewing window in the front 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 instru-
ment.
The operator controls are pushbutton membrane switches located
behind the front door of the main housing. All of them are reached by
swinging open the outer door of the enclosure. They are described briefly
here and in greater detail in chapter 4.
Figure 1-2 shows the 3000TB
­XL 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.
