Flow
to the Vent
Fig. 28: Example - Connection of the
measuring hoses

Connect the Wöhler DC 410
FLOW
with two
measuring hoses to the vent.
The overpressure socket (+) of the DC 410
FLOW
has to be connected to the aperture with the higher
pressure and the underpressure socket (-) to the
aperture with the lower pressure.
NOTE!
If the hoses are wrongly connected, the reading
will be negative. In this case inverse the hoses.


During the measurement, the Wöhler DC
410
FLOW
can be fixed to the protective grid with
a magnet, so that the results can easily be
read from the display.
