We are analog. We see angular differences, even out of the corner of our eyes. Digital (and tape) displays need to be read which requires looking directly at the gage. Also, there is the problem of resolution of the digital display. Human Factors studies validate the fact that until the screen reaches the resolution of the printed page, speed of reading, accuracy of data acquisition, and retention of data goes down directly with the drop of resolution. With an analog gage (needle rotating around a circular display), the resolution of the screen has little impact. Larry Severson Fountain Valley, CA 92708 (714) 968-9852 [email protected]
