Problem
Solution
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
•
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.
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
•
Deproteinize the sample path and condition the sensors.
Refer to
Deproteinizing the Sample Path
•
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
