PS34 Type Three Phase Multifunctional Standard meter (Improved 0.02 Level)Detailed product description：

The PS34 three-phase multifunctional standard meter adopts advanced DSP technology, wide range technology, embedded computer technology design, and temperature self balancing technology. It is lightweight, small in size, leading in indicators, rich in functions, novel in interface, easy to use, and reliable in operation. It can be widely used in the energy metering industry, energy laboratories, and other related departments, and can be used both in the laboratory and carried to the site for work.
Functional Features
Wide range measurement: Voltage signal measurement range (phase voltage) 1-480V, current signal measurement range 1mA~120A.
Multi way measurement: It can measure AC voltage, current, power (active power, reactive power, apparent power) and electrical energy in four quadrants under various wiring modes such as single-phase and three-phase Y/Δ; Reactive power and electrical energy can be measured in multiple ways, including true reactive power, cross phase reactive power, and artificial neutral point reactive power.
Multi functional measurement: In addition to measuring AC voltage, current, power, and electrical energy, it can also measure various parameters such as power demand, frequency, phase, power factor, power stability, amplitude and phase asymmetry of voltage and current, waveform distortion, spatial magnetic induction intensity, voltage drop at the same end of the electric energy meter calibration device, and the pulse constant of the tested meter's electrical energy.
Fundamental power measurement: It can be used for general full power measurement (including the power of the fundamental and various harmonics), or fundamental power measurement (only measuring the fundamental power component in signals containing harmonics).
Harmonic power measurement: can measure 2-50th harmonic power.
Harmonic analysis: It can analyze harmonics below the 50th order of power frequency voltage and current.
Electric energy error verification: It can verify the estimated values of electric energy measurement errors and standard deviations of electric energy meters and electric energy meter calibration devices.
Data and graphic display: It can intuitively display the measurement work status and various measurement data. It can visually display measured voltage and current waveform diagrams, voltage and current phase vector diagrams, and harmonic component histograms. Equipped with a 6-inch 640 * 480 dot matrix TFT true color LCD display, the display is clear and vivid, with rich colors.
Operation: Humanized design, reasonable combination of functions, "one finger key" conversion, very simple operation.
Recording and retrieval: The measurement interface can be recorded in real-time and retrieved for reference.
Wiring: The wide range current input terminal is shared, and changing the current does not require changing the wiring, making it convenient to use.
Constant: It has automatic constants (high-frequency power pulses) and arbitrary artificial constants (low-frequency power pulses).
Multipurpose: It can be used as a standard meter or as a testing device for electric energy meters. It can be used independently, communicate with a PC for remote control, and can also be equipped with a calibration device for use.
