The Heathkit Automotive Tune-up Meter CM-1073 is a vintage diagnostic tool from 1975, designed for passenger vehicles. Made by Heathkit in the United States, this analog meter comes with a case for easy storage and portability. With no warranty offered, this tune-up meter is a reliable tool for automotive enthusiasts looking to accurately diagnose and adjust the engine performance of their vehicles. Was told it worked but I do not know how to use it to test it.
