• 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.

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.
