5.7 Display Mode
The selected display mode specifies which key results are displayed
on the screen upon completion of a measurement run. Regardless of

during every measurement run. Once downloaded to the Casella
insight data management software, all measured data can be viewed.
The key displayed results set can be either configured to ISO (for
Europe) or OSHA (for U.S.A), as shown in the table below.
