Troubleshooting Failed Calibrations
Use this section to help determine causes and corrective actions for failed calibrations.
Troubleshooting Checklist for Failed Calibration
Perform the solutions in this checklist to help clear problems with failed calibrations:
• If D codes also exist for reagent problems such as D23, correct these problems first.
• Deproteinize the sample path if not done within the last week.
• If the sensor was newly installed or if maintenance was recently performed, allow
sufficient time for the sensor to equilibrate.
Perform additional calibrations.
• For pH, Na
+
, K
+
, Ca
++
, and Cl¯ sensors, if more than 2 sensors have excessive drift,
check the solution level in the reference sensor and look for salt in the vent hole,
bubbles in the sensor, or leaks.
Error
Probable
Cause Corrective Action
The parameter
has a single
line through it.
The parameter
failed
calibration.
For recommendations to resolve failed calibrations,
refer to Troubleshooting Checklist for Failed
Calibration‚ page 6-4.
View the events log to determine the event causing
the parameter to fail and follow the appropriate
corrective action for that event.
The parameter
was turned off
in Setup and
then turned on
again
Perform a 2-point calibration to make the
parameter available again.
The parameter
has 2 crossed
lines through
it.
The parameter
failed
calibration and
is unlikely to
become
available with
further
calibrations.
