Your issue may be that you have not pressed the Setup button first. Your state machine goes from Init to Wait on Setup, where the Setup button is required to transition to the Wait on Start state.
I highly recommend that you consolidate all the event structures into a single Idle state where any button can be pressed to execute the desired operation. If Setup is required before Start you can disable the Start button during init until setup is completed.
Additionally, your Running state will only execute one since there is no value wired to the timeout input of the event structure and therefore the Zone Indicator will not update to show the state of the test.
