4 Operation
Note:
When you stop pressing the UP/DOWN keys, the rapid flashing will
cease and the new span value will be acquired by the analyzer after
five seconds.
The alarms will only be nonresponsive for 60 seconds. This time-
frame allows you to reintroduce sample gas into the analyzer.
5. Immediately flow sample into the analyzer.
Supplementary Information
If, during the Span Procedure, you pressed the SPAN button by mis-
take, you must wait five minutes for the analyzer to resume analysis or you
can press the UP button and then the DOWN button. (Pressing the UP and
DOWN buttons causes the analyzer to time-out in five seconds instead of
five minutes).
If during the span procedure, you press the RANGE or ALARM
buttons:
- either the range or alarm routine will be activated.
- any changes to span will be rejected.
- the 60 second alarm delay will not occur, i.e., the alarms will be
responsive immediately.
CAUTION: TET/AI considers the action of pressing the ALARM or
RANGE buttons to be at your (the user's) discretion. The user
should be aware that the alarms will become active within 5
seconds if the range or alarm bottoms are pressed during span.
This may result in false alarms if the span gas has not been fully
purged from the cell and sample lines.
