PM310H/PM210H High-Precision AC/DC Electrical Parameter Meter

PM310H Class 0.2 / PM210H Class 0.5 high-current harmonic; AC/DC, DF, harmonic; IEC61000-3-2:2020

Introduction

The PM310H/PM210H electrical parameter test system uses digital sampling technology for waveform quantization and analysis. It is a new-generation intelligent product. PM310H is the Class 0.2 high-precision model: it uses phase-locked loop (PLL) sampling for power-frequency signals for high-precision harmonic analysis, meets IEC61000-3-2:2020 and EN61000-3-2 limit clauses, supports DF testing, and performs compliance judgment and test reporting per standard for harmonics and phase angle. PM210H is the Class 0.5 high-current harmonic analysis model: it uses PLL synchronization to accurately calculate voltage and current THD and individual harmonic values. Both have RMS and DC measurement modes, high intelligence, ease of use and good stability, and are widely used for electrical performance testing of motors, household appliances and lighting products.
