Summary

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

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 waveform 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.
