I guess this is another terminology thing. If this document is to be believed Dept of Energy Motor Document, the instantaneous peak current is the inrush current, and LRA is an RMS value. No way to get an RMS result with a one millisecond window. The inrush current will be highly dependent on the position in the AC cycle where power is applied, while the LRA should be reliably repeatable. Just what do those peak-holding meters measure: Instantaneous peak? RMS? And if RMS, how is the window defined?
