Trace Oxygen Analyzer	Introduction

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.
