PURPOSE:To ensure the checking of the electric characteristics and the quality of connection readily, by applying a pulse current whose inclination is increased or decreased to a parallel circuit of a circuit element having self-inductance component and a diode. CONSTITUTION:To both ends of the parallel circuit of the element having the self-inductance component L and the diode D, the pulse current i1 having a specified inclination of rise up and fall is applied from a pulse current generating circuit 1. By an oscilloscope 2, a voltage Vab across both ends of the circuit, which is expressed by Vab=LX(di/dt), is observed. The value is -KL at the time of rise up and KL at the time of fall (where K is a constant). Therefore, the quality of the connection of the circuit parts and the electric characteristics can be readily and positively checked in this system without removing the inductance element and visual observation. |
