D4 Codes
D4 Offset Error: pO
Problem
Sensor offset is
beyond predefined
limits during a
1-point or a 2-point
calibration.
D4 Offset Error: pH Na

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.
•
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.
•
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 K
or Ca
have an offset error, replace the fill solution
even if the fluid levels are sufficient.
•
If more than one sensor has the offset error, 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 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.
