Abstract
PURPOSE:To check the operation of a circuit easily and rapidly by providing a test point for checking the operation of the circuit on a printed substrate on which electronic parts are mounted, and printing a normal operation waveform at the test point on the printed substrate. CONSTITUTION:At a required place of the circuit of a printed substrate 1 on which parts, such as an IC3, a capacitor and resistance, are mounted, a test point 2 made of a conductive pin is provided. On the printed substrate 1, the normal operation waveform A of the circuit is printed near the test point 2. Consequently, the test point 2 is connected to a measuring instrument, such as an oscilloscope, for assembling or repairing operation and it is confirmed whether its waveform is coincident with the waveform A printed on the printed substrate 1, checking the operation of the circuit rapidly.
