I.Functions and Features

1. Multi-channel testing: Simultaneous measurement of 4 voltage channels and 4 current channels.

2. Electrical parameter measurement: It can measure a variety of electrical parameters at the same time, such as voltage, current, active power, reactive power, phase angle, power factor, frequency, etc.

3. It can measure the voltage harmonic and 2-64th current harmonic content

4. It can measure the 0.5-31.5  Inter-harmonic content of voltage and current

5. It can measure the total harmonic distortion rate of voltage and current

6. Can measure and short-term flicker (Pst), long-term flicker (Plt), voltage fluctuation

7. It can measure positive sequence voltage, negative sequence voltage, zero sequence voltage, voltage unbalance

8. It can measure positive sequence current, negative sequence current, zero sequence current, current unbalance

9. It has the function of measuring transient parameters and the function of recording voltage swells and drops. At the same time, the recording function is automatically started to record the occurrence time of the event and the actual waveforms of the five cycles before and after the occurrence.

10. It has an oscilloscope function, which can display the size and distortion of voltage and current in real-time waveforms, and can zoom in and out of the voltage and current waveforms on the instrument

11. It has a hexagonal diagram display function, which can perform vector analysis of the metering circuit and the protection device circuit, and check the wrong wiring of the metering device; in the three-phase three-wire connection mode, it can automatically judge 48 wiring methods; the automatic calculation function of the supplementary power is convenient to use. The personnel calculate the supplementary power for users with wiring problems.

12. Optional large clamp can be used to measure the transformation ratio and angle difference of low-voltage current transformers

13. Harmonic content can be displayed in the form of a histogram, with good visual effects

14. It has built-in large-capacity data memory, (storage interval 1 second-1000 minutes optional) can store data continuously for more than 18 months at a time interval of 1 minute

15. 10-inch large-screen color LCD monitor 1280×800

16. Capacitive screen touch operation is similar to that of tablet PC and smart phone, easy to learn

17. Support mouse operation, adapt to operators with different habits

18. During harmonic measurement, it can automatically judge whether the harmonic content of each order exceeds the standard according to the national standard and give a prompt, which is clear at a glance

19. It has a national standard query function for harmonic content rate, which can query the allowable value of the national standard

 20. It has a frequency measurement range of 42.5Hz-69Hz, capable of measuring 50, 60 power systems

21. Data can be stored in U disk for historical query.

22. It can be equipped with dedicated data analysis and management software to analyze and process the test results, and can grasp the power quality and load periodic changes of the measured point. This is irreplaceable for the power workers to understand the user's power quality and take corresponding processing measures effect

23. The analysis software can generate professional power quality analysis reports in accordance with the requirements of the national standard

24. The instrument has a screen capture function, and the displayed data on any screen can be manually saved in the form of pictures

25. The instrument is small in size, light in weight and easy to carry

26. It has a built-in high-performance lithium-ion battery and automatically enters the power-saving mode, allowing the instrument to work continuously for more than 10 hours without an external power supply, which is convenient for on-site testing
