Pointing Korona directly at the light source is crucial for an accurate measurement where it matters. However, reading the current value in such conditions is almost impossible. The hold mode has you covered: Tap the lower third of the screen to freeze the current measurement.

Touching down on the lower third of the screen freezes the measurement until the touch has been released. Whilst the hold mode is active, the current reading is surrounded by a rectangle.
