The uncertainty of tvc’s ac-dc transfer difference measurement

V.V. Litvikh, A.O. Nazarenko
Annotations languages:

There were analyzed ac-dc transfer difference measurement equations for thermal voltage converters (TVC). There was also analyzed the method error arising when using some equations of TVC’s ac-dc transfer difference measurement. The new measurement equation was proposed and analyzed by the authors. They have argued that when using this equation the Type B instrumental component of uncertainty at measuring TVC’s ac-dc transfer difference does not exceed 0.026 ppm.
Keywords: measurement uncertainty, measurement equation, TVC, ac-dc transfer difference
