D2 Excessive Drift: Glu Lac
D2 Excessive Drift: tHb
Problem Corrective Action
Sensor drift is
beyond predefined
limits during
calibration
operations.
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.
Problem Solution
The tHb slope drift
is beyond
predefined limits
during the
calibration.
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.
