• During this period, the reading of the pressure in the diffusion chamber
measured in Pascals (Pa) will be seen on the front screen of the MiniCapt
Mobile.
• The MiniCapt system’s diffusion chamber is designed to operate within a
specific pressure range. Should the pressure drift too high or low, a
warning will be issued.
• Further changes in the pressure may result in an alarm which will
prematurely end the test. The pressure regulator allows adjustment of
the pressure in the diffusion chamber to a value between the warning
limits as shown in the table below:
