•
First select if a negative pressure measure-
ment is to be followed automatically by a posi-
tive pressure measurement or if only a respec-
tive negative pressure or positive pressure
measurement is to be performed. Tap the re-
spective arrow accordingly.
•
If you select "negative pressure and positive
pressure measurement", the Wöhler BC 600
will automatically perform both measurements
in succession. It is not necessary to turn the
fan, as the fan changes the direction of rota-
tion.
NOTE!
DIN 13829 and ISO 9972 recommend incorporat-
ing two multi-point tests: one with positive pres-
sure and one with negative pressure. If you select
“negative pressure and positive pressure meas-
urements”, the Wöhler BC 600 automatically per-
forms both tests in sequence. It is not necessary
to make any conversions, because the fan chang-
es the direction of rotation.
However, the standard allows for creating just one
multi-point test at positive pressure or negative
pressure.
NOTE!
If only one direction is measured, the Wöhler BC
600 can also measure only one air temperature
(negative pressure measurement: inside tempera-
ture, positive pressure measurement: outside
temperature). The respective other temperature
can be manually added after the measurement to
the object data.
NOTE!
The following measurement views are independ-
ent of whether measurements are made with just
one or several Wöhler BC 600 devices. If meas-
urements are made with several devices, the val-
ues of all devices are displayed in the measure-
ment view. To view the measurement values of
