Setup/Detailed Setup
Namur Option
Click from the following:

Namur Selection: Click to enable or
disable the Namur option for the output.
(Refer to the PV Ranges/Limits chart) for
effect on output signal.

Namur Level: Displays a diagram of the
operating range and failsafe range of the
Analog output for Normal and Namur
configurations.
Sensors
Displays range information for the Sensor.
The following limits are read only:

LRL: Lower range limit

URL: Upper range limit

LTL: Lower transducer limit

UTL: Upper Transducer limit
Displays the following process variable values:

PV: The current value of the PV (primary
variable: pressure input)in user selected
engineering units

SV: The current value of the SV (secondary
variable: meter body temperature)in user
selected engineering units
Allows configuration of the process variable units.
See
Device Information menu for details.

PV Units: Click one of the pre-programmed
engineering units for the primary variable
(pressure input).

SV Units: Click one of the pre-programmed
engineering units for the secondary variable
(meter body temperature).
Signal Condition
The following signal control parameters may be
configured in this menu:

PV Damping: Enter a value for damping of
the device output. Entries may be any
floating point value from 0.00 to 32.00
seconds.

PV URV: Upper Range Value or span (input
which represents 100% output). Range of
entries is from LTL to UTL.

PV LRV: Lower Range Value or zero (input
which represents 0% output). Range of
entries is from LTL to UTL.

PV Xfer fnctn: Pressure Transfer function:

Click pressure transfer function for
calculated output:

Linear (output scaled linearly per
configured range)

Square Root (output scaled as square root
conversion per configured range - for flow
measurements)

PV % range: Displays the current value of
AO (analog output) in %
