pH Troubleshooting
Problem Solution
PPM Reading is 0 or 9.99 1. Check Flow to AKColor Flow Chamber
2. Check Chemical Levels
3. Check Discharge from DPD and
Buffer Solenoids
4. Clear Calibrations
Chemical Reagents are being 1. Check sample rate, decrease to 5 min or used too
quickly greater.
2. Check the DPD and Buffer solenoids for leaks
Measured PPM Level is lower 1. Check sample flow solenoid for leaks
than the hand check reading 2. Recalibrate the PPM reading with pH at
setpoint.
