Summary

This model measure a voltage, current, electricity and voice coil temperature of audio signal input to the speaker during load testing and record up to 100 hours.

The effective value and peak value of the entire recorded data can be displayed, and the audio signal can be played back is synchronization with the recorded waveform.

・Synchronized playback of recorded waveforms and audio signals and frequency analysis (arbitrary setting from 1/3, 1/6, 1/12oct.) are also possible.

・The effective value and peak value of the area specified by drag and drop can be displayed.

・This model can search, sort by any voltage, current, or power condition, and find the time.

・This model can save bookmarks (tagging) and comments at any time and search for them.

Optional accessories

・ODR-639 exclusive viewer software　ODR-639V

Can open a file recorded in an environment without the ODR-639/ODR-641 control unit, dedicated software that can perform frequency analysis and various analyses.
