本文讨论带有热电动势补偿装置的自动电位差计检定方法的误差。这种热电动势 E_k 对应于与热电温度计自由端相连接的电位差计接线柱的温度 t_(ko)。这种电位差计适用于测量热电动势 E_H,而 E_H 对应于热电温度计热端的温度t_(Ho)工作时,输入电位差计的电压 U_o=E_H—E_k。因此,检定电位差计时,必须考虑热电动势 E_k,为此采用了各种方法。
This article discusses the error of the automatic potentiometer verification method with thermoelectromotive force compensation. This thermoelectromotive force E_k corresponds to the temperature t_ (ko) of the potentiometer terminal to which the free end of the pyroelectric thermometer is connected. This potentiometer is suitable for measuring the thermoelectromotive force E_H, and E_H corresponds to the temperature of the hot end of the thermoelectric thermometer t_ (Ho) work, enter the potentiometer voltage U_o = E_H-E_k. Therefore, the test potential difference timing, thermoelectromotive force must be considered E_k, for which a variety of methods.
