Software does not recognize one of the
components while starting

Inaccurate liquid handling
- Prime fluid lines before using
- Check the fittings and tubes (cracks, leakage)
- Calibrate the pump
Pump turning but does not pump liquid

Invalid DO Value at day 0:
Verify that the proODO probe was properly maintained and not damaged. Assuming
that the peristaltic pump calibration, the priming and DO probe calibration were done
properly, verify that a well diluted sample pretreatment with a pH 7.0 to 7.2 at 200 °C
was used. Verify that the dilution water and the seed were prepared according to the
established methods; the QC sample was prepared according to the Glucose-Glutamic
Acid (GGA) standard. The dissolved oxygen (DO) in the seed volume is according to
the specifications. Then, restart the process. If the same case happens again, contact
