My system displays the alarm 'Clean the H₂O-sensor-refer to instruction manual'. What should I do?

This alarm automatically comes on every 2000 hours of sensor use to act as a reminder to service the H₂O probe. The H₂O sensor needs to be periodically cleaned and coated with phosphoric acid. This should typically be done about every 3-6 months. Refer to the instruction manual for directions on how to clean the probe. The alarm can be reset by navigating to the 'Common Parameters' screen, selecting 'Service H₂O Probe', resetting the counter to zero and acknowledging the alarm. It is important to note that cleaning the probe is different than calibrating the sensor.
