e) Sliding back the operating knob (150) till a dynamic stopper (20) retracts by a sliding length (23) and stops,
f) Further inserting the graduated tube (16) in the uterus (50) till the flange (20) of retracted dynamic stopper (20) again touches the cervical os (51),
g) Sliding back the operating knob (150) as much as possible, and
