Abstract

Electrical unit of resistance maintained at the Center for Measurement Standards (CMS, Republic of China) is based on the second plateau of quantized Hall resistance, RH(2). Resistors are directly or indirectly compared with the RH(2). We report the procedure of the dc and ac resistance measurements at the CMS. Uncertainties associated to the measurements are also briefly reported.

Keywords
