This video demonstrates how to use a UEI DAFM3 to measure CFM on a return filter grill. The presenter explains how to calculate the free area of the grill using engineering data from the manufacturer, and then shows how to use the DAFM3 to measure the airflow. The video also discusses the importance of allowing the AC system to run for a period of time before taking measurements to ensure the coil is saturated with water.
