7.10 Peak Memory
The peak memory function enables on-screen capture and storage in memory of the
amplitude of each A-scan acquisition. When you scan the transducer over a reflector,
the peak memory signal envelope (echo dynamic as a function of transducer position)
is retained on the screen in blue (see Figure 7-11 on page 85). The display updates
whenever a signal of greater amplitude is acquired. In addition, the current, live
waveform is displayed at the appropriate place within the signal envelope.

This function is useful for finding the peak from an indication during an angle beam
inspection.
