Figure 39: Set the [Volume] needed for ACH Result from Home screen
The [Volume] key on the “Settings” menu provides another way to enter the volume of the enclosure or
building under test.
Figure 40: Set the [Volume] needed for ACH Result from [Settings]
The key on the “Settings” menu operates exactly the same as the [Volume] key on the Home screen, but
allows the user to enter the volume without changing the “Result to be displayed” to “ACH” to make the
Home screen [Volume] key appear.
4.4 Use metric units for dimensions
The gauge determines if the user prefers entry of the dimensions using metric or imperial units based on
the choice of units for Flow or permeability results. If the “Result to be displayed” is “Flow” in CFM or any
of the permeability results with imperial units then the dimensions need to be entered in imperial units. If
the “Result to be displayed” is “Flow” in metric units or any of the permeability results with metric units
then the dimensions need to be entered in metric units.
