HPU 3612

HPU3612 Single Phase Field-testing Instrument is a digital, multifunctional, high accuracy and intelligent multi-parameter testing instrument. It not only can test energy error, but also can test voltage, current, active power, reactive power, apparent power, power frequency, power factor, phase relation and more. It is especially suitable for the inspection unit to test the accuracy of the single phase energy meter. The instrument is simple, fast, and easy to use.


  • This instrument is mainly used for the test of the single phase energy meter and the test of low voltage ratio.
  • The instrument uses the latest 32-bit 120MHz DSP technology as its core, and with 16-bit high-precision ADconverter, the error is stable, accuracy is high (has a qualitative difference with using single phase power –calibrator chip), and fully shows the advantages of digital processing.
  • Using large-screen color LCD crystal display, a screen can display all the validation set parameters, harmonics, electrical parameters and error, dynamically observing all the measurements.
  • Can use current clamp to simulate the current generated by the load, simplify field work, as well as display the terminal current, clamp current, the power, and power sum at the same time.
  • Using a 500A current clamp, and a 100A current clamp, CT ratio can be measured.
  • Harmonic analysis available (2-43 times). Voltage and current real-time waveform display can help to determine the state.
  • Calculates the energy meter constant in an energy pulse cycle.
  • It can save up to 1000 pieces of test data onto energy meters .
  • Can connect with the computer through RS232 serial communication interface.
  • With low frequency pulse output, it is convenient for self-test and inspection.
