The PQ3198 provides simultaneous measurements an inverter power quality measurements

The PQ3198 power quality analyzer is used to measure commercial power where the frequencies at 50 or 60 Hz. But it can also measure the secondary side of inverters in the following frequency ranges:
　　　　Fundamental frequency：40~70Hz
　　　　Carrier frequency：~20KHz

Parameters such as the RMS value of voltage and current, the fundamental value of voltage and current, inrush current, power, power transmission efficiency, energy, harmonics, high-order harmonics (up to 80kHz) are measured simultaneously by this device.
