DM-3104A Automatic Distortion Meter

* Automatic distortion & level measurements

This meter can quickly measure 400 Hz/1 kHz distortion and 20 Hz to 100 kHz level with push button operation. It has both readings displayed on two meters simultaneously. The fundamental frequency rejection circuit for the distortion measurement employs a filter with wide rejection range to enable accurate measurement of distortion even with signals containing wow/flutter such as those supplied from tape recorder and record player. Ideal for servicing and production of radio, tape recorder and audio products.
