Special Calibration is very similar to the PV Calibration operation. The difference is that Special Calibration adjusts the HART
transmitter's PV LRV and URV to get the consistency between the standard source ranges and loop current (CA, while digital
analog output AO is described in the PV Calibration operation). Refer to the PV Calibration operations for reference.
