How to move the number zero on my turret once I'm adjusted plz...?

Hi.

I would like to know how to move the number zero written on my turret at the zero mark please ? I have never done that and I'm afraid I will move the poi....The scope is now adjusted so I don't want to screw up

(Edited : this is NOT the way of doing it..--> ) Do I lock the turret with a small screwdriver jammed in the slot and against the wall (teeth), then unscrew the main screw, turn the turret so the zero is at the mark, lock the turret again with a small screwdriver , and screw tight the main screw ? (edited <- NO, not the way of doing it ! ) In any case , what's the best tools to do this please ?

This is a Nikon Monarch

Thanks

OK a good soul PMd me telling me the right way of doing this.

the main screw must NOT move, while the split ring with all the lines will slide to the mark if pushed.

thanks
