Show results as leakage area
Equivalent Leakage Area (EqLA) describes the leakage
area in terms of one large hole in a flat surface.
□
Press [Mode] until “EqLA” appears.
“PrA” displays the building pressure and “EqLA” shows
the combined size of all the holes in the building.
Leakage area is not a required result, but is a nice
way to visualize the size of the hole in the house.
Tubing configuration is the same as for the
depressurization test.

CFM 50 is required in the
USA. The flow displayed is
what it would be at exactly
50 Pa, eliminating the need
for an exact test pressure.
