Product Features

  • Adopting an integrated meter-source architecture, a externally mounted Class 0.02 three-phase wide-range multifunction digital reference meter is used, enabling software-based acquisition of all electrical parameters from the reference meter.
  • Employing the latest DDS technology, 36,000-point waveform synthesis, a large-scale CPLD, and a 32-bit embedded system, this signal source boasts high output stability, fine adjustment resolution, and low distortion.
  • Equipped with a 7-inch color touchscreen LCD featuring the latest RAM-based system, this display provides extensive information visualization, including three-phase voltage, current, active power, reactive power, and apparent power. It also supports displays such as power vector diagrams and waveform analysis charts.
  • It employs a high-efficiency power amplifier with an efficiency exceeding 90%, operating at a 300 kHz carrier frequency, and offers advantages such as low distortion, minimal heat generation, and high efficiency.
  • It features comprehensive protection functions, including voltage short-circuit alarm, current open-circuit alarm, and overload alarm.
  • Equipped with a high-stability, temperature-compensated crystal oscillator that outputs 500 kHz high-precision pulses, this instrument can test the clock of electric energy meters. When used in conjunction with meter calibration management software, it can measure daily timekeeping error and time-of-use switching error, among other parameters. (Optional feature.)
  • Equipped with an RS-485 communication interface, enabling various communication tests for multifunction electric meters. (Optional feature)
  • It can operate without a computer, automatically verifying electric energy meters according to its built-in procedures, and can store data for more than 10,000 meters.
  • Equipped with a USB interface, the device supports automatic firmware upgrades via a USB flash drive and data export for storage. An external mouse can also be connected for direct operation of the device.
