Question
What does it mean if the sc controller is showing "replace sensor" warning for my pHD probe?
Summary
DPD1P1 sensor warning information
Answer
The sc controllers will display a warning to "replace sensor", however this does not mean you need to replace the whole sensor. This warning is a counter that comes up yearly reminding the customer its time to change the salt bridge and cell solution of the pH probe. The warning can be cleared by acknowledging the sensor warning in the diagnostics menu.
Menu > Sensor Setup > (Choose Sensor) > Diag/Test > Counters > Reset Sensor > Are You Sure? > Enter.
