Features ■ Lowest Inductance (50uH) ■ 8 Channels ■ High voltage calibration ■ programmable impulse voltage ■ Built-in storage 200 sets testing waveform ■ Total area comparison ■ Differential area comparison ■ Wave comparison ■ Flat and Corona ■ Support RS-232, remote and printer interfaces ■ Key lock function to prevent operators from accidentally touching the keys MICROTEST 7720 is a Impulse Winding Tester that provides pulse voltage outputs ranging from 100V to 5000V. It features 8 testing channels and utilizes damping attenuation waveforms generated by L/C resonance to analyze magnetic components for defects such as short circuits between coils or between layers of winding wire. The tester offers various comparison modes, including total area comparison, area difference comparison, corona count comparison, jitter count comparison, and waveform comparison. These modes help identify and detect faulty products accurately.
