The LFM-3610 is a wow and flutter/ drift meter designed primarily for the service, testing and repair of turntables and record/playback equipment. Selectable flutter test frequency ranges permits isolating the trouble area to the capstan, motor or belt quickly and accurately. Measurements to JIS, CCIR and DIN standards are front panel selectable. The unit’s frequency selector measurement feature greatly reduces the troubleshooting and testing time normally associated with the repair of turntables and record/ playback equipment. The unit's reference frequency oscillator is crystal controlled for precise, repeatable test results. The LFM-3610 wilt measure drift, and wow and flutter either separately or combined.
