Measures Wow & Flutter and Drift Selectable JIS, cCIR and DIN Crystal Controlled Reference Oscillator Selectable Frequency Ranges for Flutter Measurements

The LFM-3610 is a wow and flutter1 drift meter designed primarily for the service, testing and repair of turntables and record.'playback equipment. Selectable flutter test frequency ranges permits isolating the trouole area to the capstan, motor or belt qurck!y and accurately. Measurements to JIS, CClR and DIN standards are front panel selectable, The unit's frequency selector measurement feature greatly reduces the troubleshooting and testing time normall associated with ?he repair of turntabLs and record, playback equipment. The unit's reference trequency oscillator is crystal controlled for precise, repealable test tesufts. The LFM-3610 wilt measure drift, and wow and fiutter either separately or combined.
