2. After replacing any component, related to the process of dilution or measurement.
3. When quality control measurements show any systematic error (bias) or they are
outside predefined limits.
4. At regular time intervals (determined by the lab itself).
5. If you want to use the instrument in Pre-diluted mode.
Calibration can be performed in two ways:
1. User can enter calibration factors – without any calibration measurements – using
the numerical keypad.
2. 1-, 2-, 3-fold or more measurements of control blood or calibrator, with known
parameters. In this case, the instrument automatically calculates new factors using
the following formula:
Assigned value x Stored factor
Measured value(s) (or average of those)
CAUTION! New calibration will invalidate the previous factors.
Old values cannot be retrieved.

7.2.1. Calibration with factors
Factor based calibration allows adjustment of primary parameters with a factor.
Maintenance
Calibration / Factors
Press white data field to modify calibration
factor. A numeric input screen will show up
so that you can enter values.
All values must be in the 0.8…1.2 range.
Press Accept to proceed with new
