PURPOSE
This standard operating procedure (SOP) covers the Calibration/Verification for the RxL
Max Dimension system.
SCOPE
This procedure applies to the Calibration/Verification on the RxL Dimension. It is vital to perform
proper calibration on the analyzer as per manufacturer instructions so as to ensure accurate results
are been obtained. You should calibrate also if any of the following occur.






Manufacturer-recommended calibration interval is due.
Before a major critical measuring project.
After a major critical measuring project.
After an event.
Per requirements.
Monthly, quarterly, or semiannually.
Calibration frequency:
Most methods required to be calibrated within 90 day for a complete calibration frequency for all
methods please refer to Appendix A

specific specification.
And QC values are within
acceptable limits
If result falls out-side assay
specific specification, and
QC values are out of
Acceptable limits.
THEN……
Proceed with
analysis
Troubleshoot the
assay and/or
instrument and
repeat calibration
1.3 Documentation
After calibration all calibration and QC run should be attached to calibration log
Sheet and must be documented on calibration log book.

2.0 CALIBRATION TROUBLESHOOTING
This section contains information on troubleshooting a calibration that has unacceptable:
If
Precision is
unacceptable
Then
 Review calibrator preparation, storage conditions,
and expiration date on the package insert sheet of the
calibrator product. For lyophilized products, the
preparation steps must be followed precisely.
 Review the instrument maintenance logs and the
System counters screen for any maintenance that
may be overdue. Check the system count for the
sample probe tip, especially if the problem is on a
method with a low sample volume.
 Check that all temperatures are within range on the
Daily Maintenance screen. Check the temperatures
with a calibrated thermometer according to the
"Calibrating Cuvette System Temperature,"
"Calibrating Reagent System Temperature," and
"Calibrating HM Module Temperature" procedures
in your operator's guide.
 If any data point are missing due to a process error:
o For logit methods, you must reject the
calibration
o For linear methods, up to three data points
can be missing as long as there is at least
one data point for each level. If the
calibration meets the criteria, it can be
accepted.
Calibration Statistics
unacceptable
 Ensure that you are using the insert sheet for the
correct calibrator lot that you are calibrating.
 Review calibrator preparation, storage conditions,
and expiration date on the package insert sheet of
the calibrator product. For lyophilized products, the
preparation steps must be followed precisely.
 Check that the sample cups were loaded into the
segment in the proper order. If they were not, you
must press F8: Reject Data and rerun the
calibration.
 Review the instrument maintenance logs and the
system Counters screen for any maintenance that
may be overdue. Check the cycle count for the
sample probe tip, especially if the problems on a

method with a low sample volume.
 Check that all temperatures are within range of the
Daily Maintenance screen. Check the temperatures
with a calibrated thermometer according to the
"Calibrating Cuvette System Temperature,"
"Calibrating Reagent System Temperature," and
"Calibrating HM Module Temperature" procedure
in your operator's guide.
 Compare the C4 term on the Calibration Review
Data screen to the C4 value on the method insert
sheet. If it is not the same, call the Technical
Assistance Center. Only logit methods have a C4
term.
Quality Control
unacceptable
● Refer to your local quality control procedure
manual.
