b) Sliding the operating knob (150) further towards the IUD end (5) till the graduated tube (16) projects out by a length of a uterine depth (45), judging by hearing an audible clicking sound produced due to the pair of locking tooth (148) negotiating with an array of inclines and notches (82) or judging by measurement markings (14) on the graduated tube (16) aligning with a flange (25) or by the position of a pointer (158) of the operating knob (150) at knob markings (95) on a cover (90),
c) Inserting the graduated tube (16) in the uterus (50) till the flange (25) touches cervical os (51) of the uterus (50),
d) Sliding back the operating knob (150) till a dynamic stopper (20) retracts by a sliding length (23) and stops,
e) Further inserting the graduated tube (16) in the uterus (50) till the flange (25) of retracted dynamic stopper (20) again touches the cervical os (51),
