On site portable design

• The equipment adopts imported protective boxes, which are lightweight, small in size, and have good protection, suitable for carrying to the site for work.

• It can be powered by 220V mains electricity or choose the built-in large capacity lithium battery mode, which is convenient for application in complex sites.

• Built in large capacity storage, it can quickly record the test data of the tested equipment on site, up to thousands of records. After the verification work is completed, it can be transferred to the supporting computer management software.

Good human-machine function

• Equipped with a large-sized LCD touch screen, the measurement value display is intuitive and the operation is very convenient.

• Multiple types of measured electricity, device errors, and phasor diagrams can all be displayed on the same screen.

Wiring recognition and graphical intuitive display

• ① Accurately measure the phase between each phase voltage and current, and visually display it in the form of a phasor diagram.

• ② Accurately measure the amplitude and phase of each phase's voltage and current, and directly display the electrical quantity value.

• ③ Automatically identify the actual results of voltage and current, including phase sequence display.

• ④ The measurement channel has oscilloscope function, which can display the waveform of the measured electricity in real time.

• ⑤ Customizable selection of single or multiple power waveforms to be displayed.

Harmonic analysis function

• ① Use a bar chart to visually display the frequency spectrum of each harmonic (with the fundamental wave being 100%).

• ② Customizable selection of power spectrum graphics to be displayed.

• ③ Display the amplitude of each harmonic.

• ④ Display the content values of each harmonic.

• ⑤ Display the phase of each harmonic.
