What to do if Hach Accessories show 'SENSOR MISSING'?
If the Hach Accessories display 'SENSOR MISSING', examine the wiring and connections for both the sensor and the module. Ensure that the terminal block is fully inserted into the module.
What to do if Hach Polymetron show 'NOT CALIBRATED'?
If the Hach Accessories display 'NOT CALIBRATED', you should calibrate the sensor.
What does it mean when Hach Accessories show 'CAL OVERDUE'?
When the Hach Accessories display 'CAL OVERDUE', it means the sensor needs calibration. Calibrate the sensor.
What to do if Hach Polymetron Accessories show 'REPLACE SENSOR'?
If the Hach Accessories display 'REPLACE SENSOR', calibrate the sensor with a reference solution and reset the sensor days. If the calibration fails, further assistance is needed.
What does it mean when Hach Polymetron display 'CAL IN PROGRESS'?
When Hach Accessories display 'CAL IN PROGRESS', return to calibration.
What to do if Hach Polymetron show 'ADC FAILURE'?
If the Hach Accessories display 'ADC FAILURE', ensure that the sensor module is fully inserted into the controller connector. If the issue persists, replace the sensor module.
What to do if Hach Polymetron Accessories display 'SENS OUT RANGE'?
If the Hach Accessories display 'SENS OUT RANGE', make sure that the sensor is configured for the correct cell constant.
What to do if Hach Polymetron show 'MEAS TOO HIGH'?
If the Hach Accessories display 'MEAS TOO HIGH', make sure that the sensor is configured for the correct cell constant.
What to do if Hach Polymetron show 'MEAS TOO LOW'?
If the Hach Accessories display 'MEAS TOO LOW', ensure that the sensor is configured for the correct cell constant.
Why do Hach Accessories show 'ZERO TOO HIGH'?
If the Hach Accessories display 'ZERO TOO HIGH', make sure that the sensor is held in air during zero calibration and is not located near radio frequency or electromagnetic interference. Also, make sure that the cable is shielded by metal conduit.
