STOPPER_CAP_VER
Stopper and cap verification on presence, seating height and applied torque, with a frozen-transducer check.
When to use it
Use STOPPER_CAP_VER when a capping or stoppering station has to prove three independent things about every closure — that it is there, that it is seated to the right height, and that it was tightened to the right torque — and reject the container when any one of them fails.
