4Ć45 Troubleshooting the System
D71 No Sample Detected at FD5
Problem
Fluid detector 5 (FD5) does not detect the sample during the predefined time limit.
Solutions
Ensure the sample volume is sufficient for the sample type.
Check the sample entry components for obstructions and the sample path for
blood clots. Remove them as described in Removing Obstructions from the
Sample Entry Components, page 4-79.
Check the CO-ox sample tubing for cracks or leaks. Replace the tubing, if
necessary, as described in Replacing the CO-ox Sample Tubing, in Section 3.
If you move the tubing or unfasten the FD5 tube locking mechanism you must
perform a manual wash to recalibrate the fluid detector.
Deproteinize the sample path as described in Deproteinizing the Sensors, in
Section 3.
Perform a two-point calibration and analyze QC materials, as necessary, to
verify CO-ox performance.
Perform the Fluidics Functions Test as described in Fluidics Functions Test,
page 4-56.
If the D code reappears, contact your service representative.
