for five minutes before timing-out. During this five minute
interval, the LED will continue to track gas through the
analyzer.
2. Flow span gas of a known oxygen concentration (between 1 and
16% oxygen) into the analyzer. The analyzer will begin to track
the span gas.
Note: The alarms will not change state during span calibration.
3. When the meter stabilizes, use the UP/DOWN arrows to adjust
the analyzer span value to the exact percent O
2
concentration in
the span gas. Remember that the acceptable range is 1 to 16% of
adjustment. The display will freeze at 1% or 16% if you try to
adjust beyond those limits.
Note: When an arrow button is first pressed, the LED begins
flashing slightly more rapidly and no longer tracks the span
gas. Instead, it responds to the UP/DOWN keystrokes.
Note: While the LED is flashing slightly more rapidly, the SPAN
routine will time-out in five seconds (instead of five
minutes), if no further keystrokes are entered.
4. When the span value is set to the known concentration of O
2
in
the span gas, stop pressing the keys and wait for five seconds.
Note: When you stop pressing the UP/DOWN keys, the rapid
flashing will cease and the analyzer will acquire the new
span value after five seconds.
The alarms will only be non-responsive for 60 seconds.
This time frame allows you to reintroduce sample gas into
the analyzer.
5. Shut off the span gas flow and immediately flow sample into the
analyzer.
6. After a few minutes, disconnect the calibration gas line and
replace the plug to cap off the calibration port.
