Abstract

PARA OBTENER EN UN DISPOSITIVO ELECTRONICO DE MEDICION (1) UNA MAYOR PRECISION DE MEDICION AL MISMO TIEMPO QUE UNA COMPENSACION DE VARIACIONES DE MEDICION, SE HA PREVISTO QUE EN UN ELEMENTO DE CORRECCION (7A), DURANTE UN PRIMER AJUSTE DEL DISPOSITIVO DE MEDICION (1), SE ALMACENE UN FACTOR DE CORRECCION (K1). PARA EL FUNCIONAMIENTO CONTINUO SE HA PREVISTO LA CONEXION ADICIONAL DE UNA TENSION DE PRUEBA (UP), QUE SE COMPARA CON UN VALOR DE REFERENCIA (R1) ALMACENADO DURANTE EL AJUSTE. SI EXISTE UNA DIFERENCIA ENTRE LOS DOS VALORES (R1, R2) SE GENERA UN NUEVO FACTOR DE CORRECCION (K1, K2), QUE COMPENSA UNA VARIACION DE SEÑAL DE MEDICION. EL DISPOSITIVO DE MEDICION (1) ES ESPECIALMENTE APROPIADO PARA CONTADORES DE ELECTRICIDAD.
