FIELD: measuring equipment.
SUBSTANCE: quick-response quasi-sinusoidal voltages amplitude meter contains a full-wave rectifier of the input quasi-sinusoidal voltage, a unipolar analog-to-digital converter, and a control device based on a microcontroller. Additionally, a peak detector and a digit key are introduced. The control device contains the data read signals issuing program into the analog-to-digital converter and the digit key control signal issuing program at time moments, determined by the specified conditions.
EFFECT: increase of the quasi-sinusoidal signal amplitude measurement accuracy due to eliminating the aperture error.
