10 Calibrating Your Analyzer
10.1 Overview
Calibration is a procedure to standardize the analyzer by determining its deviation under certain
specified conditions. In order to get accurate sample analysis results, you should calibrate the
analyzer per the procedure below when necessary.
There are two calibration programs available on this analyzer: manual calibration, calibration using
calibrators. All the parameters or part of the parameters of WBC, RBC, HGB, MCV, PLT can be
calibrated by the calibration programs.
10.2 When to Calibrate
Your analyzer has been calibrated at the factory just before shipment. It is electronically stable and
does not require frequent recalibration if you operate and maintain it as instructed by this manual. It
is recommended that you run the calibration program. You only need to recalibrate this analyzer if:
• you are going to use this analyzer for the first time.
• a major analytical component (including sample probe, syringe, etc.) has been changed.
• you are going to re-use the analyzer after a long-term storage.
• the quality control results indicate there may be a problem.
CAUTION
All of the measured parameters must be calibrated before readings of this analyzer can be
used as valid analysis results.
10.3 Checking before Calibration
Before calibration, follow the CLSI standards or your laboratory protocol to do tests, and make sure
the analyzer's background (blank count) results, repeatability results and carryover results are all
within the specified ranges.
If any of the above items is not in the range, check if the analyzer is in error. Remove the errors (if
there are) and check again. If the problem persists, contact Customer Service Department.
NOTE:
For information of blank count, repeatability, and carryover of the analyzer, see “B.4 Performance
Specifications”.
