NOTE: When the analyzer is span calibrated with less than 1 PPM oxygen,
make sure that background signal is not greater than 100 PPB. If
you attempt to span the analyzer with a higher background level,
the sensor output, which will be the sum of the background and
span gas signals, may go out of the range acceptable to the
microprocessor and an error message "CELL TOO STRONG"
will be displayed. If this occurs, press the START key to reset the
analyzer to the factory settings.
9. If you have pressed AUTO , the screen
will display the present oxygen concen-
tration, the flow rate, and the settling
time left in seconds.
• After settling, the system will wait until
the output with span gas has stabilized.
The span level will then be automati-
cally adjusted and the system will
return to the Analyze mode main menu
(step 12).
• If you press any key to abort out of
Auto settling, the span level will not be
adjusted. You will receive a warning
that settling was aborted, and the
system will return automatically to the
Analyze mode main menu.
