Fig. 53: Screen during 4 Pa test
Normally a diagram as shown in figure on the left
will appear. The pressure peaks in the diagram
are caused by the rapid movement of the window
or the door and therefore they are not relevant for
the interpretation of the diagram.
In the figure on the left the pressure drop is about
2,8 Pa.
The reliability of the system is considered suffi-
cient, when the pressure drop caused by opening
and closing the window is less or equal to 4 Pa (8
Pa in the case of wood burning depending on
room air.)
•
After the 4 Pa test is completed, click on
"Measurement OK" or "Measurement not OK"
according to the test result.
NOTE!
"Measurement OK" or "Measurement not OK" will
appear on the printout.
The analyzer will automatically enter the data
menu: "4 Pa test" will be marked by a checkmark.

To save and print the information, proceed as
