A high-performance standard energy meter for traceable applications requiring ultra-high precision (class 0.01). It has received an authoritative calibration report from the China National Institute of Metrology. It supports full function testing for fundamental and harmonic waves, used for traceable verification of energy meter testing devices. Our exclusive, patented automatic shifting technology ensures reliable performance.
Function
- Precision measurement of key electrical parameters, including voltage, current, power, phase, frequency, power factor, and harmonics.
- Provides measurement of active, reactive, harmonic, fundamental, and full-wave power, supporting power flow direction test.
- Comprehensive analysis capabilities for harmonics ranging from the 2nd to the 64th order, enabling high-precision analysis of flat-top waves, peaked waves, odd-order harmonics, sub-harmonics, and high-order harmonics in accordance with the R46 standard.
