Profile:

The KDZD3030C is a high-precision portable three-phase energy meter calibration device with an aluminum alloy casing. It integrates a 0.05-class three-phase standard meter and uses DDS waveform synthesis technology for stable, low-distortion signal output. The 7-inch color touchscreen displays real-time voltage, current, power, and vector diagrams. It supports automatic calibration without a PC, stores data for over 10,000 meters, and offers harmonic and clock error testing functions, making it ideal for field and lab calibration.

Features:

  • 0.05-class high accuracy for reliable energy meter calibration
  • 7-inch color touchscreen with intuitive operation and vector diagram display
  • DDS waveform synthesis for stable, low-distortion output
  • Supports 2~21 harmonic testing and voltage interruption tests
  • Automatic calibration without PC, stores data for 10,000+ meters
