D3 Slope Error: Glu Lac
D3 Slope Error: tHb
• If the problem persists, replace the sensor.
If the reference sensor has the slope error, the K
+
, Ca
++
, Cl¯,
pH, and Na
+
sensors will also have slope errors.
Replace the reference sensor before replacing the other
sensors.
• If the problem persists, call for technical assistance.
Problem Corrective Action
Sensor slope is
beyond predefined
limits during
calibration
operations.
Correct any reagent problems such as D23 codes before you
attempt to correct this D code.
• Perform a 2-point calibration.
Refer to Performing Manual Calibrations‚ page 3-4.
• 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.
If necessary, remove and install the sensors correctly.
• 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
Performing Manual Calibrations‚ page 3-4.
• If the problem persists, replace the sensor.
• If the problem persists, call for technical assistance.
Problem Corrective Action
The tHb slope is
beyond predefined
limits during the
calibration.
• Perform a full calibration.
Refer to Performing Manual Calibrations‚ page 3-4.
• Push on the sample chamber to ensure that it is installed
correctly and is locked in place.
• If the problem persists, replace the CO-ox sample chamber.
• If the problem persists, call for technical assistance.
