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.
•

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.
