摘要:
A method and apparatus for detecting and indicating the number of times a CRT unit arcs. The apparatus is constructed of a ferrite split toroid core wound with wire which is coupled around the focus lead and/or ground lead of a CRT through which a current spike will occur during an arcing event. The wound wire is coupled to a current pulse detector which in turn is coupled to a monostable mode timer and counter for counting the number of arcing events. The counter is coupled to a display device for displaying the number of times the CRT has arced.
