5.1 PAA Sensor Preparation
The PAA sensor supplied with the Q46 is shipped dry. It will not operate until it is prepared by
adding electrolyte and a membrane. Preparation of the sensor for operation must be done
carefully. The procedure should be done by a qualified technician, and it should only be done
when the system is ready for operation. Until then, it is best to leave the sensor in the condition in
which it is received.
