Quick Start - DeFelsko PosiTest Air Instruction Manual

The portable, hand-operated PosiTest AIR Leak Tester tests the air
barrier integrity of single, two-ply and liquid membrane systems, including
air barriers, roofing systems, waterproofing and ground liners by locating
leaks.
In accordance with ASTM E 1186, the PosiTest AIR will indicate whether
leaks exist in the test area. It is a simple pass/fail test.
The PosiTest AIR can be utilized during construction and
post-construction. The practice consists of applying a leak detection liquid
(PosiTest AIR Test Solution) to the test specimen surface, sealing a
transparent chamber around the specimen and depressurizing the
chamber with a fan.
The location of an air leak is indicated by bubbling of the Test Solution.
An estimate of the relative size of the leak can be made based on the size
and speed with which the bubbles form.
The PosiTest AIR powers up and displays dashes when the
button is pressed. To preserve battery life, the instrument powers
down after 5 minutes of no activity or by holding
