X-Y graph display lets you check the dynamic aracteristics
of inverters
• Efficiency and loss measurement function built-in
5
The operating efficiency and power loss of an inverter can be displayed when
measuring the inputs and outputs of the inverter simultaneously.
• X-Y graph display function built-in (X-axis: 1 item, Y-axis: 2 items)
By simply specifying the voltage for the X-axis and the power consumption and efficiency
for the Y-axis, you can display the dynamic characteristics of a motor in real time.
Harmonic measurement indispensable for inverter evaluation

simultaneously with power measurement)
• Noise measurement function built-in (1-channel measurement: Performed
Harmonic analysis is essential for the development and evaluation of inverters
Synchronized to the fundamental wave frequency from 0.5 Hz to 5 kHz
Harmonic analysis up to the 100th order can be performed simultaneously with
power measurement.
simultaneously with power measurement and harmonic analysis)
Noise components at up to 100 kHz can be read while looking at the measured waveforms
Simultaneously display the top 10 point frequency and voltage/current levels
Waveforms can be observed at 500 kS/s, and fundamental waves can also be checked
8
• Waveform monitoring function fully supported
• Filter function
Display the voltage and current waveforms being measured
A filter function is used to remove the carrier frequency components from the inverter,
The carrier frequency components of an inverter are also displayed in real time
and fundamental wave frequency waveforms can be checked in the waveform display.
*
The filter function is reflected in the measured values. Please
be careful when you switch to the function during measurement.
