If the calibration succeeds, the results are saved in the
system, and the system prepares to verify the
calibration.
If the calibration fails, try calibrating the instrument
again (refer to
). The
previous successful calibration is saved until the next
successful calibration occurs.
NOTE:
Canceling calibration:
You can cancel the

7.3 Verifying Calibration Daily
Verify the accuracy of the OsmoPRO MAX daily using
Advanced Instruments reference solutions and controls.
Compare the test results produced by the instrument to
expected values. Recalibrate the instrument if the test
results are outside of the expected ranges. After
recalibrating, re-run the reference solutions and controls
to verify that you obtain the expected results.
We recommend using Clinitrol 290 Reference Solution,
Protinol Protein-Based Serum Controls, and Renol Urine
Osmolality Controls. Use these reference solutions and
controls:
•
Daily, prior to testing samples, to verify instrument
operation and confirm calibration
•
After performing a recalibration
