span gas concentration:
Comment
This key sequence causes the 6400A to prompt for the
expected SO
value by pressing the key under each digit until the expected
value is set. This menu can also be entered from CALS.
ENTR stores the expected SO
Returns instrument to SAMPLE mode.
Comment
The 6400A enters the calibrate mode. External span gas should
be fed to the sample port.
Wait for reading to stabilize at span value
If you change your mind after pressing SPAN, you can still
