If the leakage value changes as a result of
J
changes made to the device (e.g., loosening or
readjusting hose connections), this can help locate
the cause of the leakage.
The displayed leakage value may differ from the
value that was determined in the leakage test. The
reasons for this are the different measuring
methods and different pneumatic ranges.
