•
Tap the button PRESSURE DIFFERENCE
(TARGET) and enter the desired value in the
dialog box that opens.
The default value is -50 Pa. This value can be
changed in the SETUP menu.
NOTE!
Generally speaking, preference should be given to
a negative pressure measurement because it is
easy to feel inflowing air and recognize leakages
accordingly. A fog spray gun is suitable for this
test, see Accessories.
A positive pressure measurement can be a wise
choice for old buildings, as this prevents noxious
substances being drawn into the interior of the
building. A fog machine is suitable for this case,
see Accessories.

To select this mode, stop measurements and
tap the field “Pressure Difference (Target)”
