Operating the Wöhler BC 600 via the app

Fig. 51: Preset options for multi-point test
The maximum target differential pressure and
steps with which the Wöhler BC 600 approaches
this pressure difference are specified. This selec-
tion corresponds to the minimum requirements to
ISO 9972.
•
Where necessary change the preset max.
target differential pressure and the number of
steps to achieve more accurate measurement
results.
•
Sequence of differential pressure steps:
Possibility to reverse the direction of the pres-
sure steps, if this is advantageous for the con-
crete measuring task.
•
Step Switching:
Manual: The next step is only started after
confirmation of the user. (e.g. manual protec-
tive pressure measurement, according to EN
ISO 9972:2018-12, Annex NA.10.3).
•
Select if a leakage test is to be initially select-
ed.
•
Then tap “CONTINUE”.
NOTE!
The CONTINUE button is only active if the user
has already selected a standard and has deter-
mined whether a leakage test should be carried
out.
NOTE!
The maximum target pressure difference and the
number of steps should be coordinated so that the
resulting step size is less than 10 Pa. If exactly 10
Pa is selected (e.g. 5 steps up to 50 Pa), there is
a risk that the step size will be larger than the
maximum step size specified in the standards due
to fluctuating environmental influences.
