– Observe the current airflow value during ongoing maintenance or check it at the latest
during the next inspection.
– If the target value is similar to the previous one, disruptive environmental influences are
the cause of the deviation. If these negative influences on the airflow monitoring cannot
be suppressed, increase the airflow range.
Notice!
The diagnostic software can be used to save in file format all the stored and current data for
the device, as well as any settings made. To be able to compare the data read out, save each
file under a different file name.
