从事电子维修的专业技术人员,基本上都拥有晶体管直流参数测试仪。该仪表不仅可以测试各种二、三极管、可控硅、场效应管的正/反向电压、正向饱和压降、放大倍数、反向漏电流等多种直流参数,还可以测试电容的耐压值;不仅可以测试压敏电阻的保护电压值,而且可以测试氖泡、霓虹灯管的起辉电压值。 Engaged in electronic maintenance of professional and technical personnel, basically have a transistor DC parameter tester. The instrument can not only test a variety of two, transistor, thyristor, FET positive / negative voltage, positive saturation voltage drop, magnification, reverse leakage current and other DC parameters, you can also test the capacitance of the resistance Pressure value; not only can test the varistor voltage protection value, but also to test the neon bulb, neon lamp of the starting voltage value.
