You can use this diagnostics parameter to read the last test result
or start an offline leakage test with which you can detect leakages
in the actuator or in the pipe installation. A test result originates
from one of the following options:
• Function "11.LEAK" has already been carried out.
• Leakage test was already carried out during initialization, see
procedure of RUN3 in chapter "Sequence of automatic
initialization (Page 117)".
• "Offline leakage test" function was already executed by a
HOST system.
"-" in the display can have the following causes:
• A leakage test has not yet been carried out.
• Resetting to the factory settings was carried out using the
"50.PRST > ALL" parameter.
• Positioner is not initialized.

are then displayed alternately for one minute.
After one minute, the display shows the difference in the actuator
position before and after the test. This means: the actuator position
has changed by the displayed value in one minute.
