介绍了100mv以下低压交直流转换标准的校准方法。为了在日本提供高精度的校准服务，我们开发了微电位器（μpot）和电阻分压器（rvd）。利用μpot和rvd对NMIJ市售的带有放大器的热传递标准（TTS）进行了低压交直流传输校准。两种方法的计算结果吻合较好。使用rvd的优点之一是，可以通过与普通比较测量相同的程序来确定交直流传输差异。
Calibration methods for low-voltage ac-dc transfer standards below 100 mV are described. Aiming to provide high-accuracy calibration services in Japan, we have developed micropotentiometers (μpots) and resistive voltage dividers (RVDs). Low-voltage ac-dc transfer calibrations of a commercially available thermal transfer standard with amplifiers (TTS) at NMIJ were performed using both the μpots and RVDs. The results of the two methods are in good agreement. One of the advantages of using RVDs is that the ac-dc transfer differences can be determined by the same procedures as ordinary comparison measurements.
