ATTMA: TS-1 is a UK standard is similar to DS/EN 13829. However, it has the Air Leakage Index added,
which uses the same units as permeability except it uses the exposed envelope area rather than the
total envelope area that permeability requires.
1. Press
[Mode]
key to scroll to the “Flow/Area” mode
2. Press
[Enter]
and input either the Envelope Area to display Air Permeability or the Exposed
Envelope Area to display Air Leakage Index, as specified in the standard
3. Press
[@ Pressure]
to display the Flow @ 50 Pa, Air Changes @ 50 Pa, and either Air Permeability or
Air Leakage Index @ 50 Pa
4. In order to record both Air Permeability and Air Leakage Index, re-enter the different areas from
steps 1 and 2. Results may be read directly from the gauge.
Title-24 is a California standard. It is used to measure duct leakage in CFM at 25 Pa under
pressurization, and house leakage at 50 Pa under pressurization.
1. Assess and measure the Conditioned Floor Area CFA in sq ft as specified in the Standard.
2. Press
[Mode]
to scroll to the “EqLA/Area” mode.
3. Press
[Enter]
and input the CFA as measured in step 1.
4. Press
[@ Pressure]
to display the Flow @ 25 Pa.
5. Results for default, heating only analysis may be read.
6. “EqLA/Area” may be read directly from the gauge.
LEED is a multi-point test so the gauge is used to take multiple readings which are recorded in turn.
Each reading on the gauge measures a single-point pressure of the enclosure. The gauge can also
provide a quick single-point check of the enclosure as follows:
1. Press
[Mode]
key to scroll to the “Flow/Area” mode.
2. Press
[Enter]
and input the Envelope Area to display Air Permeability as specified in the standard.
3. Results may be read directly from the gauge.
