控温标准电池是稳定可靠、使用方便的电压参考标准。随着精密电测量和高精度数字电压表发展的需要,控温标准电池亦相应地普及起来。使用单位及计量部门对如何验收和检定控温标准电池都很关心。本文先介绍标准电池电动势与温度的关系,阐明检定控温标准电池的原理,结合实例说明一般检定控温标准电池的程序,最后指出常见现象及其解决办法。
Temperature control standard battery is stable and reliable, easy to use voltage reference standard. With the development of precision electrical measurement and high-precision digital voltmeter needs, temperature control standard battery is also popularized accordingly. The use of units and measurement departments on how to check and test temperature control standard batteries are very concerned. This paper first describes the relationship between the standard battery electromotive force and temperature to clarify the principle of verification temperature control standard battery, combined with examples of general verification temperature control standard battery program, and finally points out the common phenomenon and its solution.
