Isolation measurement system DM-8000H
|
The input
block, control block and display block are isolated with optical fiber cables. |
|
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) |
|
Measurement using long memory. (DM-900A/AL, DM-910A/AL) |
|
Simultaneous
measurements of the inverter's switching waveform and ON-voltage. |
