1. Obtain CalChek solution tubes as needed according to the table
above.
2. Gently invert the tubes one or two times to mix the solution.
3. Remove the cap from each tube, and then place the tubes on the
Calibration rack according to the table above making sure that the
barcode labels are placed at the correct positions.
4. Load the Calibration rack onto right side of the iChemVELOCITY
sampler.
5. The rack will be processed and all calculations performed
automatically. The CalChek liquid reagents can be re-used within
eight (8) hours.
6. When the CalChek is successful, the date/time of the new SG/CC
CalChek will be displayed on the shift summary screen.
7. The SG/CC CalChek status (Pass/Fail) can be reviewed in the QC
Review screen.
8. The measured values are compared to acceptance ranges stored in
the system. If all the values fall within the appropriate ranges, the
CalChek is verified and found acceptable.
