In the power analyzer's function menu, there is a "Routine Analysis" function. After entering the "Routine Analysis" function, you can click the "Measurement" button on the interface. At this time, the waveform on the instrument interface will stop refreshing.

At this time, the waveform on the instrument interface will stop refreshing. Then, you can select the number of waveform frames to view through the menu, and the recorded waveform will be displayed on the screen. You can then zoom in and out of the waveform or perform measurement and analysis on the waveform, just like operating an oscilloscope.
Wide range of values
Ordinary sensors and instruments can generally only guarantee measurement accuracy within a narrow range. When the range of the measured signal is wide, multiple sensors are usually used in conjunction with a range switch to broaden the measurement range. The WP3000 frequency converter power analyzer has eight range settings within a single sensor. Each range measures only 50% to 100% of the signal within that range, achieving high-accuracy measurement within a range of 1% to 200% of the rated input. Thanks to seamless range switching technology, data is not lost during range switching, meeting the needs of dynamic measurements over a wide range.
Wide phase range
Taking motors and transformers as examples, the power factor is very low under no-load conditions, and the input power at this time is often the main loss of the equipment. High-accuracy measurement under low power factor is an important technical indicator for evaluating high-efficiency products such as motors and transformers. The phase angle error index of sensors and instruments directly affects the accuracy of power measurement; the lower the power factor, the greater the impact of the same phase angle error on the accuracy of power measurement. Most instruments and meters use a power factor of 1 as the reference condition for power measurement accuracy, without specifying the accuracy index under low power factor conditions, which are difficult to measure. Most sensors used for variable frequency power measurement do not specify phase indexes, and the phase error of the system is unclear. At low power factors, the accuracy of power measurement is unknown. AnyWay series variable frequency power measurement/metering products have extremely small phase angle errors in voltage and current measurements, achieving high-accuracy measurement in the power factor range of 0.05 to 1.
