1. It can measure various electrical parameters such as voltage, current, active power, reactive power, phase angle, power factor, and frequency.

2. The vector diagram of the measured voltage and current can be displayed, and the user can obtain the correctness of the wiring of the measuring equipment by analyzing the vector diagram.

3. The current is measured with a clamp transformer. Because the clamp-type current transformer is used for measurement, the operator can conveniently and safely perform the measurement without disconnecting the current loop. According to the different measurement range of the user, it is possible to choose clamp meters with different ranges.

4. It can measure and analyze the AC power quality supplied by the public power grid to the user. Its measurement analysis: frequency deviation, voltage deviation, voltage fluctuation, flicker, three-phase voltage allowable unbalance and grid harmonics

5. Single-phase voltage and current waveforms can be displayed and three-phase voltage and current waveforms can be displayed simultaneously.

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

7. Load fluctuation monitoring: measure and analyze the fluctuations caused by various power-using equipment to the power quality of the public power grid under different operating conditions. Regularly record and store changes in power parameters such as voltage, current, active power, reactive power, apparent power, frequency, and phase.

8. Dynamic monitoring of power equipment adjustment and operation process to help users solve problems that occur during the adjustment and commissioning of power equipment.

9. Able to test and analyze the dynamic parameters of reactive power compensation and filtering devices in the power system and make quantitative evaluation of its functions and technical indicators.

10. Different storage interval time can be set, and data can be continuously stored according to the set time interval;

11. Built-in large-capacity data memory, which can be continuously stored for more than 18 months at a 1-minute interval, which can meet the needs of long-term monitoring test points.

12. The instrument has a USB interface, which can easily copy the data directly to the background management computer.

13. Cooperating with powerful data management software, real-time sampling data can be directly uploaded to the background management computer for more comprehensive and faster processing in the background.

14. With perpetual calendar, clock function, real-time display date and time. The test data and results can be saved at the same time as on-site inspection, and uploaded to the computer through the serial port, and the computerized management of data can be achieved through the background management software (optional accessory), with powerful report functions.

15. Adopt large-screen imported color LCD as the display, English operation interface and LCD display interface with English character prompt information, multi-parameter display, friendly man-machine dialogue interface.

16.3 minutes of no operation LCD display automatically enters the power saving mode, in order to maximize the battery operating time.

17. Conductive silicone keys, good hand feel, long life, reasonable design and easy operation.

18. Built-in large-capacity, high-performance lithium ion rechargeable battery, fully charged for more than 10 hours of continuous operation.

19. Small size, light weight, easy to carry, can be used for on-site measurement, and can also be used as standard measurement equipment in the laboratory.
