Overview

GAOTek Portable Electricity Hour Meter Calibration Device is suitable for metering and testing centers of power grid companies, power management departments of power supply companies, national energy metering and testing institutions at all levels, as well as industrial and mining enterprises and electricity meter manufacturers for quick and small batch testing of all kinds of single and three-phase electricity meters. It can also be used as a high-standard power source. The device adopts a high-precision power frequency AC collector composed of two digital signal processors (two DPS for signal processing and one for power acquisition and calculation) and a 16-bit high-speed digital-to-analog converter, and then combines the ARM processor and the operating system as the operation control platform. The new generation of portable three-phase electricity meter calibration device is developed.

Features

  • Integrate the meter and source to detect the error of various three-phase single-phase watt-hour meters and the error of moving words
  • After setting the experimental point, the internal automatic gear shift needs no human intervention
  • The core circuit related to the precision has anti-corrosion, dustproof and moisture-proof shielding treatment, the accuracy of long-term stability is higher
  • Super strong electromagnetic compatibility processing mechanism
  • Cooperate with electromagnetic experimental equipment to detect other measurement standard products
  • Can give positive and negative active power, positive and negative reactive power
  • Apparent power to provide pulse output, and the constant is programmable output
  • Provide LAN, RS232, USB and other communication interfaces
  • 7-inch TFT display interface is clear
  • Provide machine software communication protocol interface to establish automatic verification and detection system for secondary development
