Abstract

다수의 전압을 갖는 신호를 측정하기 위해서, 다수의 신호를 소정전압 이상의 고압 신호와 그 이하의 전압신호로 구분하고, 다수의 채널을 통해 고압신호 스위칭부 및 저압신호 스위칭부에 인가하고, 그 내부에 구비된 릴레이를 스위칭하여, 하나의 신호를 선택하여 고압신호 강하부 및 저압신호 강하부에 인가하여 고압신호 스위칭부(저압신호 스위칭부)저항과 고압신호 강하부(저압신호 강하부)의 저항비에 의해 입력신호를 측정에 맞는 신호로 강하한 후, 고압신호 버퍼부(저압신호 버퍼부)를 통해 신호를 안정화시켜 멀티플렉서부에 인가한다.In order to measure a signal having a plurality of voltages, the plurality of signals are divided into a high voltage signal of a predetermined voltage and a lower voltage signal, applied to the high voltage signal switching unit and the low voltage signal switching unit through a plurality of channels, and the inside thereof. By switching the relay provided in the circuit, one signal is selected and applied to the high voltage signal dropping section and the low voltage signal dropping section to apply the resistance of the high voltage signal switching section (low voltage signal switching section) and the high voltage signal dropping section (low voltage signal falling section). After dropping the input signal to a signal suitable for the measurement by the ratio, the signal is stabilized through the high voltage signal buffer (low voltage signal buffer) and applied to the multiplexer.

멀티플렉서부는 제어부의 제어신호에 의해 상기 고압신호 버퍼부와 저압신호 버퍼부에서 입력되는 두 신호중 하나를 선택하여 측정장치에 인가한다.The multiplexer unit selects one of two signals input from the high voltage signal buffer unit and the low pressure signal buffer unit according to a control signal of the controller and applies it to the measurement apparatus.
