e
For an overview on calibration, see Calibration on page A-28.
For performing individual calibrations, see Performing calibrations on page B-65.
By default, all calibrations that are due or will be due within the forecast period are
taken into account during the Prepare phase.
Make sure that you have read and understood section Safety information on page B-5. The
following warning messages in particular are relevant:
o Injury through reagents and other working solutions on page B-5.
o Infection by biohazardous materials on page B-5.
Skin inflammation caused by reagents
Direct contact with reagents may cause skin irritation, inflammation, or burns.
When handling reagents, be sure to wear protective equipment and observe the cautions
given in the Instructions for Use.
Incorrect results due to expired calibration
Calibrations are performed to compensate for changes over time in reagents and in the
measurement systems. Failing to perform calibrations when they are due may lead to
incorrect results.
Make sure to perform calibrations when they are due.
Incorrect results due to wrong tube placement
Be sure to place the calibrators in the specified positions.
