RMS VOLTAGE METER Russian patent published in 1994 - IPC

FIELD: measurement technology. SUBSTANCE: meter has amplifiers 2, 4, filter unit 3, RMS value detector 6, and display unit 8. Resistive divider 9, differential voltage comparators 11, 12, one-shot multivibrators 13, 14, multiplexor 15, NAND gates 16, 17, and OR gate 19 introduced in meter make it possible to transmit current values of RMS voltage and controlled amplifier transfer ratios over single channel. Multichannel display unit is not required. Meter is built around standard integrated circuits. Improved accuracy of measured voltage is ensured by separating high-accuracy scale section. EFFECT: simplifier design. 6 dwg
