Isolation measurement system DM-8000H

 

The input block, control block and display block are isolated with optical fiber cables.
(DM-900A/AL, DM-910A/AL)

Frequency bandwidth: DC to 500MHz.

Simultaneous multi-channel measurement of many channels of different reference potentials. (2 to 24 channels) (DM-900A/AL)

Long-life battery drive. (The system can be driven by three batteries for about 12 hours)
(DM-900A/AL, DM-910A/AL)

Measurement using long memory. (DM-900A/AL, DM-910A/AL)

Simultaneous measurements of the inverter's switching waveform and ON-voltage.
(DM-910A/AL)

   

*Distribution of DM-8000H series are limited in Japanese and Asian market.
