1. Multi-channel measurement: 4 voltage channels and 4 current channels measured simultaneously.
2. Electrical parameter measurement: can simultaneously measure voltage amplitude, current amplitude, phase, frequency, active power, reactive power, power factor, and other parameters;
3. Can measure voltage and current harmonic content from 2nd to 64th order;
4. Can measure total harmonic distortion rate;
5. Can measure short-term flicker (PST), long-term flicker (PLT), and voltage fluctuation;
6. Can measure positive-sequence voltage, negative-sequence voltage, zero-sequence voltage, and voltage unbalance;
7. Can measure positive-sequence current, negative-sequence current, zero-sequence current, and current unbalance;
8. Transient parameter measurement function, with voltage sag/swell event recording, and automatically starts waveform recording to record the time and actual waveform of the event;
9. Oscilloscope function, can display voltage and current waveforms in real time, showing magnitude and distortion, and can zoom in/out on the instrument;
10. Six-phase diagram display function, can perform vector analysis of metering circuits and protection device circuits, and check for incorrect wiring;
11. Optional large clamp meter can measure the ratio and phase angle error of low-voltage current transformers;
12. Harmonic content can be displayed in bar chart form for good visual effect;
13. Built-in large-capacity data storage (storage interval selectable from 1 second to 1000 minutes), can continuously store for more than 18 months at 1-minute intervals;
14. Supports mouse operation, adapting to operators with different habits;
15. During harmonic measurement, it can automatically determine whether each harmonic content exceeds the national standard and give a prompt, making it clear at a glance;
16. Harmonic content ratio national standard query function, can query the allowable values of the national standard;
