CAUSE
CORRECTIVE ACTION
Electrode dried out
Soak the electrode in 3M KCL solution at least 20 minutes.
Measured value is out of range
Check the electrode whether clogged, dirty or broken.
Incorrect pH buffer solutions
Using the fresh pH buffer solutions for calibration.
Electrode is broken
Replace the electrode.
