9.3 How to Calibrate
The analyzer provides 3 calibration programs: manual calibration, calibration using
commercial calibrator and calibration using fresh blood samples. Two sets of calibration
factors are prepared respectively for the whole blood mode and the predilute mode.
9.3.1 Preparing Your Analyzer
Do the following pre-calibration procedures before calibration. If problems are detected
during these checks, do not attempt to calibrate the analyzer. If necessary, call Mindray
customer service department or your local distributor for assistance.
Check and make sure there are enough reagents for the calibration. You need to start over
the calibration if the reagents run out during the process.
Do the background check. If the analyzer alarms for abnormal background results, see
Chapter 11 Troubleshooting
Your Analyzer
for solutions.
Enter the “

” screen and run a vial of normal control 11 consecutive times. Enter the
“
Review
” screen to check the reproducibility of the second to eleventh runs and make sure
they meet the following requirements.

immediately run the diluent three consecutive times, calculate the carryover per the following
equation.
