Problem
Sensor offset is
beyond predefined
limits during a
2-point calibration.
D5 Codes
D5 No Endpoint: Ca
Problem
Sensor does not
reach stable reading
during predefined
time limit.
The patient sample
result for the
affected sensor is
reported as question
result (-----?).

Corrective Action
Correct any reagent problems such as D23 codes before you
attempt to correct this D code.
•
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 biosensor.
•
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.
•
Ensure that the measurement module door was not opened
during analysis.
If door was opened, repeat the sample analysis.
•
Perform a 2-point calibration.
Refer to Performing Manual Calibrations‚ page 3-4.
•
If a D5 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 D5 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.
