Test Key
The Test key is only active when the system is ready. Ultrasonics are enabled while the Test key is pressed,
and disabled when released. Test performs the run, seek, and store functions, causing the power module to
test for the resonant frequency of the converter and tool at 10% amplitude, and then go to the amplitude set-
ting.
