If you perform a whole blood measurement calibration, it is recommended to run a blank measurement
before the calibration procedure (see chapter 1).
Cleaning: Perform cleaning or hard cleaning if:
High blank results are experienced
Clogging related flags are consistently appearing with measurement results
After service actions or service level maintenance
Measurement results or QC results are drifting (perform hard cleaning)
Clog formation in the tubing (first remove any plugging or contamination)
Reagents incorrectly connected to the wrong place
