Nippon System Technology

Advantages
The static characteristics (electric characteristic) of motors can be measuredcollectively.
The connection of wiring is required just once because measurement circuits areselected automatically.
The contents and order of measurements can be set freely.
Being saved automatically, measurement results can be recorded securely.
