Solution
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.
•
Check that the sensors 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.
•
If the problem persists, replace the sensor.
•
If the problem persists, call for technical assistance.

Corrective Action
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.
•
Deproteinize the sample path and condition the sensors.
Refer to Deproteinizing the Sample Path‚ page 5-4.
•
Check the solution level in the affected sensor and look for
bubbles.
+
++
The K
, Ca
, and Cl¯ sensors should be nearly full. The pH
+
and Na
sensors should be full. If the solution level is low,
refill the sensor.
•
If more than one sensor or the reference sensor has the slope
error, look for salt in the vent hole and bubbles in the sensor.
•
Clean and remove bubbles from the reference sensor as
needed.
•
Check that the sensors 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 sensor contacts and measurement block for salt
buildup.
•
Check behind the sensor for fluid leaks that can come from
the reference sensor.
If salt or leaks are present, clean the sensor with water, dry,
reinstall, and perform a 2-point calibration. Refer to
Performing Manual Calibrations‚ page 3-4.
