Corrective Action
Correct any reagent problems such as D23 codes before you
attempt to correct this D code.
•
If the sensor was newly installed or if maintenance was
recently performed, allow sufficient time for the sensor to
equilibrate.
•
Perform additional calibrations.
•
If the glucose sensor is > 30 days old or the lactate sensor is
> 5 days old, replace the sensor.
•
Check that the biosensors are installed in the correct location
and are aligned, the O-rings are in place, and the
spring-loaded latch is closed.
•
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 water, dry,
reinstall, and perform a 2-point calibration. Refer to
Recalling Calibration Results‚ page 3-4.
•
If the biosensor has been installed less than 1 day, perform
2-point calibrations as necessary.
•
If the problem persists, replace the sensor.
•
If the problem persists, call for technical assistance.
Solution
Correct any reagent problems such as D23 codes before you
attempt to correct this D code.
•
Perform a full calibration.
Refer to Performing Manual Calibrations‚ page 3-4.
•
If the problem persists, replace the CO-ox sample chamber.
•
If the problem persists, call for technical assistance.
