Quickstart Guide Trace Oxygen Analyzer

Function Keys:

Six touch-sensitive membrane switches are used to change the specific function performed by the analyzer:

•Analyze Perform analysis for oxygen content of a sample gas.

•System Perform system-related tasks (described in detail in chapter 4, Operation.).

•Span Span calibrate the analyzer.

•Zero Zero calibrate the analyzer.

•Alarms Set the alarm setpoints and attributes.

•Range Set up the 3 user definable ranges for the instrument.

Data Entry Keys:

Six touch-sensitive membrane switches are used to input data to the instrument via the alphanumeric VFD display:

•Left & Right Arrows Select between functions currently displayed on the VFD screen.

•Up & Down Arrows Increment or decrement values of functions currently displayed.

•Enter Advances VFD display to the next screen in a series or returns to the Analyze screen if none remain.

•Escape Backs VFD display to the previous screen in a series or returns to the Analyze screen if none remain.

Digital Meter Display:

The meter display is a Light Emitting Diode (LED) device that produces large, bright, 7-segment numbers that are legible in any lighting. It produces a continuous readout from 0-10,000 ppm and then switches to a continuous percent readout from 1-25%.

Alphanumeric Interface Screen

The VFD screen displays values, options, and messages for immediate feedback.

Set Flow:

Needle valve used to adjust flow of gas sample

Flowmeter:

Monitors the flow of gas past the sensor. Readout is 0.2 to 2.4 SLPM of nitrogen.

Standby Button:

The Standby turns off the display and outputs, but circuitry is still operating.

Access Door:

For access to the Micro-fuel Cell,the front panel swings open when the latch in the upper right corner of the panel is pressed all the way in.
