switch between gases in synchronization
with the analyzer’s operation.
3000ZA-M:
This model has current output signals (4-20-
mA) for ppm range and range ID, in
addition to voltage outputs.
3000ZA-V:
Gas flow through the cell block in this
model is driven by vacuum downstream
from the cell block instead of upstream
pressure. The internal restrictor is located
downstream from the cell block to support
this configuration. All other standard
features are present in this model.
1.5 Front Panel (Operator Interface)
The standard 3000ZA is housed in a rugged metal case with all
controls 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.
