of the scrubber (if one is installed).
3. Set the flow rate to 2 SCFH using the knob on the sys-
tem front panel and press ACK.
4. Press AUTO to let the system determine the settling

stant, and then press ACK.
6. After step 5, the system will automatically span to the
user-entered span value. If the zeroing is successful, the
main Analyze mode menu will appear as in step 10.
