前言在毛主席无产阶级革命路线指引下,我国社会主义革命和社会主义建设取得了很大成就,工农业生产愈来愈趋向机械化、自动化。这样,我厂生产的PZ8直流数字电压表在科研部门,计量部门,以及各工矿企业中的应用也日益增多。由于数字电压表还是一种比较新的测量仪表,有些使用单位对它的了解、掌握的程度还不深,特别是出现故障后,不知如何及时排除故障,因此有部份使用单位,希望我们编写一些有关PZ8数字电压表的使用、常见故障的排除及修理方法的资料,作为使用和修理数字电压表时参考。
Foreword Under the guidance of Chairman Mao’s proletarian revolutionary line, great achievements have been made in the socialist revolution and socialist construction in our country. Industrial and agricultural production has become more and more mechanized and automated. In this way, I plant the PZ8 DC digital voltmeter in the scientific research departments, measurement departments, as well as the industrial and mining enterprises in the growing number of applications. As the digital voltmeter is still a relatively new measuring instrument, some use the unit to understand it, the degree of grasping is not deep, especially after the failure, I do not know how to promptly troubleshoot, so there are some units, I hope we can write Some information on the use of PZ8 digital voltmeter, troubleshooting and repair of common faults, as a reference when using and repairing digital voltmeter.
