Main Functions

• High Measurement Accuracy: Power and energy measurement accuracy level 0.05 level Voltage and current measurement accuracy level 0.05, can be used for metering and calibration of AC quantities, harmonics, and dynamic performance.
• Wide Measurement Range: Measurement Range 30-420V, 50mA-120A Meets the traceability and calibration requirements of dynamic performance of AC electric energy meters, harmonic electric energy meters, and AC meters.
• Automatic Range Switching, High Integration: Voltage 30-420V uses a pair of terminal inputs, current 50mA-120A uses a pair of input terminals, full range automatic range switching ensures accuracy indicators of the measurement range.
• Synchronous Sampling of Voltage and Current: Voltage and current use synchronous sampling technology, under the control of a synchronous clock, sampling voltage and current values at the same moment, calculating power and energy by dot product method, eliminating metering errors caused by asynchronous sampling of voltage and current, improving the accuracy of energy metering.
• 2~50 Harmonic Measurement Harmonic Measurement Accuracy 0.2% Meets current JJG 1106-2015, AC dynamic performance, IR46 test requirements.
• 24-bit High-speed ADC: Uses industry-leading 24-bit ADC chip and multi-core DSP processor + DDR large capacity memory, high sampling rate, strong computing power, high accuracy.
• High Annual Stability Uses high-precision imported components, typical annual measurement stability value is 100 PPM/year Can be used for years without calibration.
• Measurement Value Statistical Analysis: Can statistically analyze amplitude, power values, minimum value, variation, standard deviation, helping analyze short-term stability and change trends.
• Human-Machine Interaction: Equipped with large-size touch display screen Clear and intuitive value display, equipped with RJ45, RS232, USB interfaces, convenient for building automatic test systems.
