The 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 meter’s structure simply and measure 0.02% accuracy of the relative error.
Measuring error of three phase voltage, current, power and electric energy error ≤±0.02%
Voltage from 5V to 480V
Current from 10mA to 120A
Testing three-phase voltage, current, power, electric energy, power factor, phase and frequency synchronously
Three-phase four wire (3P4W) & three phase three wire (3P3W) active
Three-phase four wire (3P4W) & three phase three wire (3P3W) reactive
Three-phase four wire (3P4W) & three phase three wire (3P3W) cross connected reactive
Single phase two wire (1P2W) active & Single phase two wire (1P2W) reactive
Single phase three wire (1P3W) active & single phase three wire (1P3W) reactive
Two-phase three wire (2P3W) active & two phase three wire (2P3W) reactive
Testing waveform distortion factor and 2nd - 21st harmonic content and displaying rod chart.
Measuring the asymmetry rate of voltage, current and phase in every phase and the stability of power.
Display voltage and current waveform synchronously.
Energy pulse constant can be set automatic or manual, calculating and displaying the error and standard deviation of tested meter; have the function of electricity quantity add up, power on/off can be controlled by manual or external Synchronous pulse
Through software can calibrating full range and phase angle to improve the reliability and efficiency
There are two communication ports RS-232 and RS-485, can be connected to PC and test bench, realizing automatic measurement and calibration
