Conventional electromagnetic relays use a waveform display device such as an oscilloscope to measure the time from the time the contact closes until the armature contacts the core (this is called the armature follow operation time), and the contact opening/closing signal is measured using a waveform display device such as an oscilloscope. The current waveform of the coil is displayed, and measurements are made visually from these. For example, the third
As shown in the figure, the armature follow operation time is measured by driving the electromagnetic relay coil 3 by the electromagnetic relay drive circuit 8, and using the waveform of the coil current converted to voltage by the current-voltage conversion circuit 9. A means is used for observing the contact opening/closing signal waveform obtained from the electromagnetic relay contact detection circuit 12 which converts the opening/closing state of the electromagnetic relay contact 4 into voltage using an oscilloscope 13.
