4Ć19 Troubleshooting the System
D3 Slope Error:
Glu Lac
Problem
Sensor slope is beyond predefined limits during a one- or two-point calibration.
Qualifiers: Glu Lac
Solutions
NOTE:ĄĂ If D codes also exist for reagent problems such as D23, D24, D29, or
D50, correct these problems first, then correct this D code.
Perform a two-point calibration.
Check the expiration dates and the levels of the reagents. Ensure that the bottles
are installed properly and in the correct location. If reagents have expired, are
low, or are incorrectly installed, replace the affected reagents, and perform a
two-point calibration.
Check that the biosensors are installed in the correct order and are aligned, the
O-rings are in place, and the spring-loaded latch is closed as described in
Removing and Checking the Sensors on page 4-65.
Check the biosensor contacts and measurement block for salt buildup. Check
behind the biosensor for fluid leaks that can come from the reference sensor. If
salt or leaks are present, clean the sensors with reagent water, dry, and perform
a two-point calibration after reinstalling the biosensors.
Perform the Measurement Test for the affected biosensor as described on page
4-70.
If the glucose or lactate biosensors have been on the system less than one day,
then perform three two-point calibrations.
Replace the glucose or lactate biosensors as described in Replacing the Glucose
and Lactate Biosensors in Section 3.
If the D code reappears, contact your Service Representative.
