How to change the pipe diameter for E+ H72 series vortex flowmeters

How to change the pipe diameter for E+H 72 series vortex flowmeters? If I use 375 to make the change, why can’t the write protection status be changed either? There are two areas that can be modified; only the MATING PIPE DIAMETER can be changed, but the flow rate becomes lower after making that change? Can’t the NORMAL DIAMETER be changed at all? How to do it? Asked for advice?
Write protection is a DIP switch; whether write protection is on or off, that setting cannot be changed
First, you need to enter the password 4685; otherwise, it’s not possible to change the k-factor or the caliber. However, if you modify these values on your own and the resulting certificates do not match, the manufacturer will not be responsible for the accuracy of your measurements, and the previous calibration certificates will become invalid, which can be very troublesome if discovered. I hope you will consider it carefully.
