Chapter 9 Calibration
The H50/H51 Hematology Analyzer has been calibrated prior to delivery. However, errors may
still be introduced to the system during transport or installation. To maintain the accuracy and
precision of this analyzer, Edan recommends that QC test needs to be conducted prior to being
used for sample analysis for the first time and after every repair and maintenance of the analyzer.
If the QC test fails, which is not caused by the improper operation or the controls, the analyzer
needs to be calibrated.
NOTE:
Only the calibration materials provided by EDAN or its authorized distributors should be
used.
