SZ-03A-K8F series three phase standard meter utilize such lasted technology as high speed DSP, CPLD,MCU and ADC with self-calibration, etc. Thus, the meter can sample AC signal in high speed and treat them with special digital arithmetic. All of these make the meter’s structure simply and measure 0.02% accuracy of the relative error.
1. High precision and long-term stability
2. Universal unit for many applications
3. Measuring various kinds of electric parameters in the three-phase or single-phase circuit synchronously
4. Calculating directly the reactive power makes the phase place very accurate in angle measurement
5. Three energy constants only, leads to simple calibration and reliable result
6. Have the function of low frequency pulse input to calculate the error
7. Vector diagram display
8. Waveform display for voltage & current of each phase
9. Analysis and display of harmonic
10. Rs232 and Rs485 interface, can be operated by computer system
