DeFelsko PosiTest AIR Manual De Instrucciones página 7

Careful observation is important as bubbles of
different sizes can form anywhere within the test area
where solution is present. Bubbles may also form
and pop quickly. A very large leak may not form a
bubble, but rather blow solution away.
When a leak has been identified, the test can be halted by pressing the
button. In Automatic mode, the PosiTest AIR will automatically stop
when the pre-selected pressure limit is reached.
Let the pressure within the test chamber decrease before removing it
from the test surface. The test area can then be marked for further repair,
or the bubble can be photographed if documentation is required for the
particular job.
Upon completion of the test, the maximum pressure differential and
duration of the test will flash on the display.
