Abstract

본 발명은 시스템의 호출신호 측정시험이 가능한 호출신호 시험장치에 관한 것으로 이를 해결하기 위하여 피측정호출신호 발생장치의 출력단과 계측장비의 입력단에 상호 접속가능하고, 제어스위치와 제1,2가 변저항에 의해 측정된 신호를 계측장비에 표시할 수 있도록 신호를 인가하는 호출신호 시험장치에 있어서; 피측정호출신호 발생장치의 출력단(21,22)과 계측장비의 입력단(31,32)상이에 병렬 연결되어 상기 호출신호 시험장치의 스위치(SI)가 오프될때 피측정호츨신호 발생장치의 정상부하 및 최대부하시의 호출신호출력에 대응되게 저항값을 가변하는 제1가변저항; 피측정호출신호 발생장치의 출력단 (21,22)과 계측장비(30)의 입력단(31,32)사이에 병렬 연결되어 호출신호 시험장치의 스위치(si)가 오프되고, 스위치(S2)가 온될때 피측정호츨신호 발생장치의 과부하경보를 시험할 수 있도록 저항값을 가변하는 제2가변저항; 제1, 2가변저항에서 인가되는 정상부하와 최대부하 및 과부하 경보를 상기 계측기에 표시하는 표시수단을 포함하도록 구성된다.The present invention relates to a call signal test apparatus capable of measuring a call signal of a system, and to solve this problem, the control terminal and the first and second variables may be interconnected to an output terminal of a measurement signal generator and an input terminal of a measurement apparatus. A call signal test apparatus for applying a signal to display a signal measured by a resistance on a measuring instrument; Normal load of the signal to be measured signal generator when the switch (SI) of the call signal test device is turned off in parallel between the output terminals 21 and 22 of the call signal generator to be measured and the input terminals 31 and 32 of the measurement equipment. And a first variable resistor varying a resistance value corresponding to the call signal output at the maximum load. A parallel connection is made between the output terminals 21 and 22 of the call signal generator under measurement and the input terminals 31 and 32 of the measurement equipment 30 so that the switch si of the call signal test apparatus is turned off and the switch S2 is turned on. A second variable resistor for varying the resistance value so as to test an overload alarm of the apparatus under test signal generation under test; And display means for displaying a normal load, a maximum load, and an overload alarm applied to the first and second variable resistors to the measuring instrument.
