Abstract

PURPOSE: To discriminate quality of a glow switch easily and quickly, by generating a high voltage pulse through the operation of the glow switch and comparing the pulse width and high voltage level of the high voltage pulse with the reference value.
CONSTITUTION: A kick voltage produced between both ends of a glow switch 6 is input to a kick voltage measuring circuit 7, the pulse width and voltage level of the kick voltage are measured, the mumber of times when the pulse width and the voltage level at the production of the start signal exceed the specified value preset, is counted and the count data is transferred to the microcomputer 9. Further, the kick voltage measuring circuit 7 informs the production of failure high voltage pulse when the pulse width and voltage level of the kick voltage exceed preset conditions, to the microcomputer 9. when the pulse width of the kick voltage is 2μ or more and the voltage level is 600V or more, the glow switch 6 is judged as good.
