Corrective Action
Correct any reagent problems such as D23 codes before you
attempt to correct this D code.
• Ensure that the measurement module door was not opened
during analysis.
If door was opened, repeat the sample analysis.
• Perform a successful calibration (1-point or 2-point).
Refer to Performing Manual Calibrations‚ page 3-4.
• If a D6 occurs during sample analysis, repeat the sample.
• Deproteinize the sample path and condition the sensors.
• Refer to Deproteinizing the Sample Path‚ page 5-4.
• Check the solution level in the affected measurement 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 a D6 occurs for more than one sensor, check the solution
level in the reference sensor and look for salt in the vent hole
and bubbles in the sensor.
• Clean and refill the reference sensor as needed.
• Check the sensor contacts and measurement block for salt
buildup.
• Check behind the sensors for fluid leaks.
• 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.
• If the problem persists, replace the sensor.
• If the problem persists, call for technical assistance.
