YJZV-1型直流标准电流电压源在检定精密直流电工仪表过程中作为一种电源被使用,其组成部分主要包括:基准源、保护电路、稳压电源及输出显示等。但在该设备使用过程中也往往会出现一些问题或故障,给检定工作带来麻烦。笔者通过多年工作经验现就该设备经常出现的一些故障和调修方法总结如下,以供参考。量程100mA是该仪器的基本量程,所以在一般情况下(即排除明显短路,烧保险丝等故障后),检测故
YJZV-1 DC standard current and voltage source in the verification of precision DC electrical instrumentation as a power supply is used, and its components include: the reference source, the protection circuit, power supply and output display. However, some problems or malfunctions often occur during the use of the equipment, which brings trouble to the verification work. The author through years of work experience now on the equipment often appear some fault and repair methods are summarized below for reference. Range 100mA is the basic range of the instrument, so under normal circumstances (that is, excluding obvious short circuit, burning fuses and other failures), the test
