Any possibilities to Rearrange a ROSEMOUNT 3051CD Differential Pressure Transmitter for 0-300 inH2O if the Range Limits is -250 to +250 inH20. currently Transmitter is Factory calibrated for 0 to 235 inH2O.
 
Tables A-1 and A-2 on pages 118-119 of the 3051 manual shows the LRL and URL range 'limits' (not range values LRV and URV) for 'range 2' to be -250in H2O to 250in H2O, as you have pointed out.

The text says, "Zero and span values can be set anywhere within the range limits stated in Table A-1, Table A-2". LRV and URV are the zero and span values. It doesn't mention having the LRV or URV exceed the LRL or URL values. I doubt the communicator will let you range outside the limits.

Even if you can re-range the URV to 300in H2O, the reference accuracy spec is out the window and you're on your own.
