7.If AUTO was chosen in step 6, wait for the O2 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 O2 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
O2 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
