Region of Interest (ROI) Snapshots in Merlin™

By Matthew Kahane · July 15, 2026

← Back to White Papers

Abstract

Power Quality recordings are the primary source of evidence in any PQ investigation. The problem is that these recordings can be weeks long and contain hundreds of captures, which makes sorting through them all a time-consuming process. PMI’s newest addition to Merlin™ allows it to reference and embed clickable snapshots directly into its analyses, taking the reader straight to the relevant evidence, whether that is a zoomed graph, a waveform, or an event table. This paper covers what a region of interest is, how Merlin™ identifies one, how it surfaces that region as a snapshot, and how to find these snapshots in PQ Canvass.
