3020M-C: In addition to all standard features, this model also has
separate ports for zero and span gases, and built-in
control valves. The internal valves are entirely under the
control of the 3020M electronics, to automatically switch
between gases in synchronization with the analyzer's
operations
1.5 Operator Interface
All controls and displays on the standard 3020M are accessible
from outside the housing. The instrument has two simple operator
controls. The operator has constant feedback from the instrument
through an alphanumeric display, a digital oxygen meter, and a sample
flow meter. The displays and controls are described briefly here and in
greater detail in chapter 4. Figure 1-1 shows the standard 3020M with
without the optional gas panel. Figure 1-2 is the same instrument with a
gas panel.
