Abstract :
The SI value of the quantized Hall resistance based on Electrotechnical Laboratory´s (ETL) calculable capacitor is presented. Some improvements for previous measurement systems were made and some of the measurement techniques were changed. Based on measurements of ETL, the value of h/e2 is estimated to be 25,812.8064 ΩSI with a systematic uncertainty of 0.24-p.p.m. root-sum-square (r.s.s.) and a random error of 0.11-p.p.m. at one standard deviation (1σ)
