How an Overhead Projector (OPH) Is Used
An overhead projector (OPH) is a device that is used to cast a transparency image on a screen. The process of using OPH involves a number of steps. First, OHP is placed on a table, which is positioned several feet from a screen and plugged into an electrical socket. Next, a transparency face is placed up on the plate glass surface of OPH, and the switch of OPH is turned on. Finally, the height of OPH is adjusted so that an image is centered on the screen, and the focus knob of OPH is turned until the clear image is projected.
