1. The instrument is a high-precision testing device specifically designed to detect power quality issues such as waveform distortion, harmonic content, and three-phase imbalance in the power grid; It also has the functions of electrical parameter testing and vector analysis.

2. It can accurately measure various electrical parameters such as voltage, current, active power, reactive power, phase angle, power factor, frequency, etc.

3. It can display the vector diagram of the measured voltage and current, and users can analyze the vector diagram to determine the correctness of the wiring of the measuring equipment.

4. The current is measured using a clamp type transformer. Because when using a clamp type current transformer for measurement, the operator does not need to disconnect the current circuit, making the measurement convenient and safe. According to the different measurement ranges of users, clamp gauges with different ranges can be selected.

5. It can measure and analyze the quality of AC power supplied by the public power grid to the user end, including frequency deviation, voltage deviation, allowable three-phase voltage imbalance, and grid harmonics.

6. It can display single-phase voltage and current waveforms and simultaneously display three-phase voltage and current waveforms.

7. All test interfaces have a screen lock function to facilitate user reading and data analysis.

8. Measurable short-term flickerPstLong term flickerPlt.

9. Load fluctuation monitoring: measuring and analyzing the fluctuations caused by various electrical equipment in different operating states on the power quality of the public grid. Regularly record and store the changing trends of power parameters such as voltage, current, active power, reactive power, apparent power, frequency, phase, etc.

10. Record the active and reactive energy consumed at the testing point.

11. Dynamic monitoring of power equipment adjustment and operation process, helping users solve problems that arise during the adjustment and operation of power equipment.

12. Be able to test and analyze the dynamic parameters of reactive power compensation and filtering devices in the power system, and make quantitative evaluations of their functions and technical indicators

13. Different storage intervals can be set to continuously store data according to the set time intervals;

14. Built in large capacity data storage, with storage intervals ranging from3Seconds to10Minute adjustable; pressA 1-minute time interval can store continuously for more than 18 months, meeting the needs of long-term monitoring and testing points.

15. The instrument is equipped withUSB interface allows for easy copying of data directly to the backend management computer.

16. In conjunction with powerful data management software, real-time sampling data can be directly uploaded to the backend management computer for more comprehensive and rapid processing.

17. optionalWIFI(Bluetooth)Module, remotely control the instrument using a tablet or smartphone.

18. Equipped with perpetual calendar and clock functions, real-time display of date and time. At the same time as on-site testing, test data and results can be saved and uploaded to the computer through a serial port. The data can be managed by a microcomputer through backend management software (optional accessories), which has powerful reporting functions.

19. Adopting a large imported color LCD screen as the display, the Chinese operation interface is equipped with Chinese character prompt information and a multi parameter display LCD display interface, making the human-machine dialogue interface friendly.

20. After 3 minutes of inactivity, the LCD display automatically enters power-saving mode to maximize battery life.

21. Conductive silicone buttons have good tactile feel, long lifespan, reasonable design, and easy operation.

22. Built in large capacity, high-performance lithium-ion rechargeable battery, capable of continuous operation when fully chargedMore than 10 hours.

23. Small in size, light in weight, easy to carry, can be used for on-site measurement, and can also be used as standard measuring equipment in laboratories.
