ППТН-1型电位計系用来对低阻电势进行精密測量的一种仪器,在电工测量热工測量,以及其他非电量的电測量方面应用很广;因为它的測量电势范圍在20毫伏以下,用一般的檢定方法根本不能讀出它的准确数字,因此,这种精密电位計的檢定是一个相当不簡单的問題。国家計量局电学处,自今年2月开始研究用比較法检定这种精密电位計,在具体試驗过程中迂到的一些困难,如:热电势的消除,灵敏度的提高,正反方向的誤差太大等等。我們都在党的正确领导下,苏联专家的热情帮助下,特別通过反右傾、鼓干勁的学习后,破除迷信,打破了我們的自卑感,在試驗过程中,党一再鼓舞我們的微小进步, An instrument of the type ППТН-1 is a device used for the precise measurement of low resistance potentials, which is widely used in electrical measurement thermometry and other non-electrical measurements because of its measuring potential in the range of 20 mV In the following, the exact number can not be read by the usual test methods. Therefore, the verification of such a precision potentiometer is a rather inconvenient one. National Bureau of Metrology Department of Electrical, since February this year began to study the use of comparative method for the determination of this precision potentiometer, in the specific test circuitous some difficulties, such as: the elimination of thermoelectric power, increased sensitivity, positive and negative error too Big and so on. With the correct leadership of the party and with the help of the Soviet experts, we have been able to break the superstition, breaking our sense of inferiority, especially through the anti-rightist and energetic study. In the course of the experiment, the party has repeatedly inspired our slight progress ,
