对现在仍在使用的半自动电位差计可以用不同的方法进行检定。在“检定规程”附录中给出了两种检定方法。第一种,用低阻高电势电位差计和它进行直接示值比较;第二种,用高阻高电势电位差计,但必须采用分别测量两个标准电阻线圈电压值的方法进行示值比较。这种方法也是半自动电位差计企业标准中规定的方法。 Semi-automatic potentiometers still in use can be calibrated in different ways. Two methods of verification are given in the Appendix of the Verification Protocol. The first, with a low resistance high potential potentiometer and its direct indication comparison; the second, with high resistance and high potential potentiometer, but must be measured by two standard resistance coil voltage value of the method of indication Compare This method is also the method specified in the enterprise standard for semi-automatic potentiometers.
