搜尋常見問題

In PM5000 meter, different Powers are calculated based on RMS V, I, and PF. Please note PM5000 meter is capable to calculate True RMS. It means the RMS value is calculated considering all the harmonics that the meter can detect. Hence in the Power calculation also all the harmonics are included.

The formula to calculate True RMS is;
