Abstract :
The possibility of using high-resolution digital voltmeters for ac voltage measurements at a frequency of about 16 Hz is presented. The method for the determination of correction factors in phase difference measurements with two synchronised voltmeters is described, and a level of uncertainty of 0,1 /spl mu/rad is achieved.
