CAUSE
CORRECTIVE ACTION
Electrode dried out
Soak the pH electrode in 3M KCL solution for 15 minutes
Soak the Ion Selective Electrode in the diluted standard solution
Soak the conductivity electrode in tap water for a few minutes
Measured value is out of range
Check the electrode whether clogged, dirty or broken
Incorrect calibration solutions
Using the fresh calibration solutions for calibration
Setting value does not match calibration solution
Reset the calibration value
DO electrolyte solution is depleted
Refilling electrolyte solution
Zero oxygen solution is contaminated
Replace the calibration solution
pH electrode is out of service life
Replace the pH electrode
Keypad is not working properly
Replace the batteries
