Part II: 4-1

Operation

4.1

Introduction

All operation (except observing the flowmeter), including testing, and

configuring the analyzer to your process/application, is performed from the
Control Unit and is described in Part I, Chapter 4 Operation, of this
manual.

To take advantage of the automatic calibration feature, the proper

calibration gases must be connected to Zero and Span ports, and held
within the proper pressure range, as described in chapter 3 Installation.
Calibration gas considerations are reviewed in section 4.3.

Testing consists mostly of running the built-in Self Test, and checking

the status of the Micro-Fuel Cell sensor.

4.2

Flowmeter

Although all operation is controlled from the Control Unit, at times

during operation or setup it is necessary to observe the flowmeter, which is
located on the Analysis Unit. The flowmeter monitors the flow of gas past
the Micro-Fuel Cell sensor. The scale on the flowmeter is graduated from
0.2 to 2.4 standard liters per minute (SLPM). Flow readings between 0.1
and 2.4 SLPM are acceptable.

4.3

Calibration Gases

The calibration procedures are described in Part I: Control Units

section 4.4, The Zero and Span Functions.

The analyzer is calibrated using zero and span gases. Any suitable

oxygen-free gas can be used for zero gas as long as it is known to be
oxygen free and does not react adversely with the sample system.
