The CL3112E is a high-precision, multi-functional, three-phase multifunctional standard meter with a maximum current rating of 200A. It is designed for the testing and calibration of energy meters, power terminals, and other electric power measuring instruments. It can also be used for the traceability of Class 0.05 and lower-grade energy meter verification devices, as well as other metrological equipment.
Function
- It can measure the distortion factor of voltage and current for each phase, as well as analyze the 2nd to 64th harmonics.
- It is capable of measuring all waveforms specified in Recommendation R46, including peak-top waves, flat-top waves, odd harmonics, subharmonics, high-order harmonics, and zero-crossing waves.
