Product ID: 3104B, 3204B Automatic Distortion Meter 3104B 1CH. Distortion Meter. 3204B 2CH. Distortion Meter. The meter can speedly measure 400Hz / 1KHz distortion (0.01%) and 20Hz to 100KHz level with push butter operation. As an automatic distortion meter, this model is ideal for adjustments and inspections on the mass production lines of radio, tape recorders and other audio products. The distortion and level are indicated simultaneously on two meters. The fundamental frequency rejection circuit for the distortion measurement employs a filter with a wide rejection range to enable the accurate measurement of the distortion even with signals containing wow / fluther such as those supplied from tape recorders, record players and other equipment.
