PURPOSE:To adjust easily an idealized diode circuit by installing a short-circuit means at an anode and cathode of a diode of the idealized diode circuit and make short-circuit the diode by the short-circuit means at the time of adjustment. CONSTITUTION:When the circuit is adjusted, set value es is supplied as the input signal ei to a non-inversion input terminal 4 of an arithmetic amplifier OP. The section between a terminal T1 and a terminal T2 is short-connected by a conductor with a detachable alligator clip. Under this condition , a variable resister 2 is made to be variable, and the resister 2 is fixed at the zero point where the output signal eo of an output terminal 3 is precisely determined at one point. Namely, the signal equivalent to the value es supplied to the terminal 4 of the amplifier OP and the value supplied through the register 2 by the reference signal er are precisely equal. Under this condition, when the short circuit of the terminals T1 and T2 is released and the free input signal is added to the terminal 1, the output signal from the terminal 3 can be zero at the precise set value as es or below and at the value es or above the signal can be positive. For this reason, the circuit can be easily adjusted. |
