FA Mode (TR and IR)

A simplified differential-imaging mode for quick fault localization.

Key features:

Camera Image Display — grab (hand), zoom (magnifier, SHIFT-CLICK to zoom out), and area select (square, used with the merged image to crop to ROI) tools.
Output Voltage Control — device voltage and output source.
Camera Histogram — brightness, set previously in Project Manager.
Thermal Image Display — calculated thermal image; scale bars compress the scale.
ROI Statistics — Temperature Value (ΔT); CTR or E (material coefficient, user-entered); Scale Bars; ROI Tools (rectangle, annulus, freehand, point).
Region Mean Graph — history of measured ROIs; ideally within 5% before stopping; right-click "clear chart" to reset.
