connect to pressure calibator, apply the low pressure -60
adjust the span into low pressure and then apply the high
pressure then adjust the span screw into high value. it is
calibrated in the range of -60 to -20.

if it is the SMART transmitter its easy, just apply URV and
LRV value through Communicator then connect to the pressure
calibator then check URV, LRV and intermediate value

A DP transmitter is used to measure the level of an open tank. The drain line of the tank is connected to a control valve, and is configured as, if the level of the tank is 90% the valve should get open 10%. And if the tank level is 10%, the valve should get open 90%. Draw wiring diagram and explain how to configure DP transmitter and control valve using HART communicator. If the span error at output is 1%, what will be the %opening of the control valve at 60% level of the tank?
