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
check the solution level in the reference sensor and look for salt in the vent hole,
bubbles in the sensor, or leaks.
