Abstract
A method and apparatus relating to generating, by at least one motion sensor of a data acquisition device that is mounted to a door having a door closer, motion data indicative of motion as the door is moved from an open position to a closed position, generating, by at least one load cell of the data acquisition device, load data as the door is being opened, analyzing the motion data and load data by a central processing device, determining at least one adjustment to the door closer based on at least one of a duration the door was in each of a plurality of door movement zones, as determined using the motion data, and a force applied to open the door, as determined using the load data, and displaying at least one installation instruction corresponding with the at least one adjustment on a graphical user interface of the central processing device.
