Determining PV Characterization
ATTENTION
Series 8 Analog Input channels do not support the HART PV Characterization
(HPVCHAR) parameter. These configuration options are selected using the
PVCHAR parameter.
The PV signal received from the field is characterized based on the entries that you make
for the parameters:
SENSRTYP
PVCHAR
PVTEMP
INPTDIR, and
TCRNGOPT
The input PV signal is converted to a raw PV signal (PVRAW) whose units can be %,
ratio, millivolts, microvolts, or milliohms depending on the entry made for the
SENSRTYP parameter, and then converted to the engineering units.
The engineering unit conversions that are performed in the ANALOG INPUT, ANALOG
INPUT WITH HART, and TC/RTD points are listed in the table below.
