Class 0.02 Single Phase Multifunctional Standard CL1112D

CL1112D is a high-precision, multi-functional, cost-effective single-phase reference energy meter developed in compliance with Recommendation R46 issued by the International Organization of Legal Metrology (OIML). It is designed for use in the testing and calibration of energy meters, power terminals, and other electrical measuring instruments, and for the traceability of energy meter verification devices and other metrological equipment.

Function

It can measure the distortion factor of voltage and current, 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.
