3.    Standard Meter


3.1 General Introduction

SZ-03A-K8 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 meters structure simply and measure 0.02% accuracy of the relative error.
