If the calibration . . .
is successful
is not successful
Then . .
go to step 5.
a. Clean the sample chamber.
Refer to Cleaning the
Sample Chamber in
Section 3.
b. Check that the hemolyzer
is correctly assembled and
that the gasket is in place.
c. Perform a pH/lytes
one-point calibration and
then perform a tHb slope
calibration.
d. Analyze the sample again.
e. If the message reappears,
go to step 6.
4. Review the last calibration.
5. Obtain and analyze a new sample from the patient.
6. If the message reappears, the problem may be the result of
the patient’s clinical condition. Analyze a sample from a
different patient.
7. If the message reappears, contact your Service
Representative.
Insufficient COox
Sample The CO-ox sample chamber does not detect the sample during
the predefined time limit. The CO-ox measurement cannot be
completed.
1. Ensure that the sample volume is sufficient for the
sampling device used and the tests requested.
2. Ensure that the sample is red, i.e., a blood sample or a
colored aqueous solution.
3. Check the CO-ox sample path for leaks, cracks, or loose
connections. See Replacing the CO-ox Sample Tubing in
Section 3.
4. Check the CO-ox sample path for obstructions. Remove
obstructions, as described in Removing Obstructions from
the CO-ox Sample Path in Section 4.
5. Verify that the CO-ox pump is operating correctly and test
the flow rate of the CO-ox pump, as described in the Pump
Functions Test in Section 4.
