Product Overview

Product Features

  1. This instrument is a high-precision testing device specifically designed to detect power quality issues in power grids, including waveform distortion, harmonic content, voltage fluctuations and flicker, and three-phase imbalance; it also features electrical parameter measurement and vector analysis capabilities.
  2. It can accurately measure a wide range of electrical parameters, including voltage, current, active power, reactive power, phase angle, power factor, and frequency.
  3. It can display vector diagrams of the measured voltage and current, allowing users to determine whether the metering equipment is wired correctly by analyzing these diagrams.
  4. Current is measured using clamp-on current transformers. This method allows operators to perform measurements conveniently and safely without having to break the current circuit. Depending on the user’s measurement range, clamp meters with different ranges can be selected.
  5. It can measure and analyze the quality of AC power supplied from the public grid to the user end, including frequency deviation, voltage deviation, voltage fluctuations, flicker, permissible three-phase voltage unbalance, and grid harmonics.
  6. It can display single-phase voltage and current waveforms, as well as three-phase voltage and current waveforms simultaneously.
  7. All test interfaces are equipped with a screen-lock function to facilitate reading and data analysis.
  8. Load Fluctuation Monitoring: Measures and analyzes the fluctuations in power quality caused by various electrical loads on the public power grid under different operating conditions. It periodically records and stores the trend changes of electrical parameters such as voltage, current, active power, reactive power, apparent power, frequency, and phase.
  9. Dynamic monitoring of power equipment adjustment and operation processes helps users resolve issues that arise during equipment adjustment and commissioning.
  10. Capable of testing and analyzing the dynamic parameters of reactive power compensation and filtering devices in power systems, and of conducting quantitative evaluations of their functions and technical specifications.
  11. Different storage interval times can be set, and data will be continuously stored at the specified intervals.
  12. It features a built-in high-capacity data storage unit that can continuously record data at 1-minute intervals for more than 18 months, thereby meeting the requirements of long-term monitoring at test sites.
  13. The instrument is equipped with a USB interface, enabling convenient direct data transfer to the backend management computer.
  14. When used in conjunction with powerful data management software, real-time sampling data can be directly uploaded to the backend management computer for more comprehensive and faster processing.
  15. Equipped with a perpetual calendar and clock function, it displays the date and time in real time. While conducting on-site testing, it can simultaneously store test data and results and upload them to a computer via the serial port. With the optional background management software, data can be managed digitally on a PC, and the system offers robust reporting capabilities.
  16. It features a large-screen, imported color LCD display with a Chinese-language operating interface, complete with Chinese character prompts and multi-parameter display, providing a user-friendly human–machine interaction interface.
  17. The LCD display automatically enters power-saving mode after 3 minutes of inactivity to maximize battery life.
  18. Conductive silicone keys offer a pleasant tactile feel, long service life, rational design, and convenient operation.
  19. Equipped with a high-capacity, high-performance lithium-ion rechargeable battery that delivers over 10 hours of continuous operation on a full charge.
  20. Small in size and lightweight, it is easy to carry and can be used both for on-site measurements and as a standard metrological instrument in the laboratory.
