Phase 3: The valve moves to the user-defined
points valid for phase 1 one after the other.
This is plotted in a sound level vs. travel
graph. The graph shows where the point of
activation is and to which value the 'Activa-
tion level' must be reduced to allow the test
to be completed successfully.
Defining parameters
1. Switch to manual mode.
2. Define parameters for repetition test. See
Note concerning changing measured
points.
3. Start repetition test.
The start of the repetition test is docu-
mented in the Time stamp.
'd9' and 'tEST' are indicated in alternat-
ing sequence on the positioner display.

Cancel the repetition test by right-clicking
'Stop test' and selecting 'Execute' or by
pressing the rotary pushbutton at the posi-
tioner ('Test status' = Test cancelled manual-
ly). After the repetion test has been canceled,
the positioner remains in manual mode.
In TROVIS-VIEW the test status and progress
flag of the repetition test are displayed.
When the repetition test has been successful-
ly completed, the 'Test status' reading indi-
cates 'Test completed successfully'.
