Calculate motor power, motor efficiency, and inverter output power after measurement using high-speed waveform calculations and display the results using the instrument's X-Y display function. The ability to use the X-Y display for waveform calculation results as well as input signals from measurement units means you can perform a broad range of analyses. Additionally, X-Y analysis can be performed at user-specified areas of the recorded fluctuating waveform, since you can choose waveform areas for generating an X-Y display.
