Abstract :
20 precise compact voltage sources based on Zener diodes were manufactured. These sources were under investigation at measuring system in NPO VNIIFTRI during the year. A few sources with voltage drift less than 5 ppm per year and noise level lower than 100 nV in the frequency band of 0.01-10 Hz were selected for manufacturing of 4-channels dc voltage transportable reference standard. This reference standard was investigated by Russian I-V Josephson systems.<>
