Slide the probe across the steel block. Sound pulses fire into the metal; echoes
bouncing off the side-drilled holes and the back wall appear as triangles
on the scope — the further the reflector, the further right the echo.

Pick an angle, then tune GAIN / RANGE / METV like the real unit.
About this demo — This is a simplified, web-interactive version of the Python
ultrasonic-testing program I wrote. The testing block has been reduced to a plain rectangle
with drilled holes, because real ultrasonic calibration blocks (such as the
IIW block, standardized by the International Institute of Welding) are proprietary,
patented designs. It still gives a strong impression of what the full
USM 32 simulator does.
