Operations 4

7.If the O2 cell current is too large to be zeroed, an error message will appear. Press ACK to retry or ESC to abort the zeroing process.

8.If AUTO was chosen in step 4, wait for the O2 level to settle before the system zeros. This may take from thirty (30) seconds to fifteen (15) minutes, depending on the sample gas oxygen level.

9.After a stable low oxygen level is detected by the sys- tem, the system will automatically zero.

If the O2 cell current is too large to be zeroed, an error message will appear (see step 7). You will then have to press ESC to abort, or ACK to retry.

10.If the zero is successful, the system will return to the main Analyzer mode menu.
