Abstract :
The national standard of volt in Estonia is based on the ten solid-state references and consists of maintenance and transfer modules. Traceability of the dc voltage standards is obtained by annual calibration of 4 Zener units fitted in the transfer module. The calculated expanded uncertainty is less than 10 muV, taking into account the component due to predicted annual drift of the 10 V system average
