ABSTRACT:
A method and arrangement for measuring and recording parameters relative to the onset of coagulation and the build-up of film resistance within an electrodeposition bath system. A rapid voltage rise across the bath system is detected by the arrangement, the rapid rise indicating the onset of coagulation, and the parameters are recorded. Parameters are further recorded by the arrangement during the period of build-up of film resistance.
