7. If AUTO was chosen in step 6, wait for the O
2
level to
settle before the system spans. This may take from fif-
teen (15) to thirty (30) minutes or longer, depending on
the sample gas oxygen level.
Go to step 11 if MAN was chosen in step 6.
8. If any key was pressed in step 7, the screen indicates
that the span has been aborted. Press ACK to retry
spanning, or ESC to abort the span.
9. After the system has automatically detected sensor sta-
bility, the system will automatically span. If the system
spans correctly, the next screen will be the Analyze
mode main menu (see step 14).
10. If the O
2
cell current is too strong or too weak to be
spanned, an error message will appear. Insure that the
span gas concentration has been entered correctly. Press
ACK to retry, or ESC to abort the span.
11. If MAN was pressed in step 6, watch the logger or the
O
2
value on the screen to determine when the output is
constant, and then press ACK.
12. After step 11, the system will automatically span to the
user-entered span value.
