Testing the Redox Sensor
CAUTION!
Correct sensor operation / Run-in time
Damage to the product or its surroundings
–
Correct measuring and metering is only possible if the sensor is working per‐
fectly
–
Please read the operating manual for the sensor
–
It is imperative that the run-in times of the sensors are adhered to
–
The run-in times should be allowed for when planning initial operation
NOTICE!
Testing the Redox Sensor
With redox measured variables, the sensor is not calibrated but tested according to
its design
–
Observe any notification of abnormal behaviour when testing the redox sensor
–
Should the test not be successful, replace the redox sensor
