Adjust the HART transmitter's PV LRV and URV to get the consistency between the standard source range and digital
analog output (AO). To perform the PV Calibration operation, proceed as follows:
1. In the HART diagnostic and service interface, choose PV Calibration from the list, then press Enter or Select to show
the PV Calibration Setting Interface (Figure 11.9).

Press Enter or Done to view the PV Calibration Process interface (Figure
11.10). Note that the calibrator will judge whether these input values are
available for the transmitter before starting the PV Calibration Process.
4. The PV calibration process allows you to calibrate the lower (0%) and
upper (100%) range values LRV and URV) have been previously set in
PV Calibration Setting interface. Located at the top of the PV Calibration
interface is the error summary table (Figure 11.10 and Figure 11.11). Once
the calibration is complete (Figure 11.11), the PV range adjustment
information will be displayed at the bottom of the interface. You can
decide whether to adjust PV range. To reject, press Esc or Reject, to
adjust Press Enter or Adjust.
