Fluid detector 1 (FD1), fluid detector 2 (FD2), or both detectors do not detect fluid during a one-point
or a two-point calibration.
Qualifiers: 7.3 6.8 Wash Cal G/L
Solutions
NOTE:ĄĂIf a D23 code also exists, correct that problem first, then correct
the D24.
Check for cracks or leaks in the sample tubing.
Replace the sample tubing, if necessary, as described in Replacing the Sample
Tubing in Section 3. Perform the Fluidics Functions Test as described in
Fluidics Functions Test, page 4-56.
Check that the sensors are installed in the correct order and are aligned, the
O-rings are in place, and the spring-loaded latch is closed as described as
described in Removing and Checking the Sensors on page 4-65.
Check the expiration dates and the levels of the reagents. Ensure that the
reagent bottles are installed properly and in the correct location. If reagents
have expired, are low, or are incorrectly installed, replace the affected reagents,
prime the system, and perform the Fluidics Functions Test as described on
page 4-56.
Deproteinize the sample path as described in Deproteinizing the Sample Path in
Section 3.
Perform the Fluid Detector Test as described in Fluid Detector Test, page 4-66.
Perform the Fluidics Functions Test as described in Fluidics Functions Test,
page 4-56. If the D24 code disappears, perform a two-point calibration.
If the D code reappears, contact your Service Representative.
