Setup
Namur Option
Select from the following:
Namur Selection: select 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: Select one of the pre-programmed engineering
units for the primary variable(pressure input).
SV Units: Select 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:
Select 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
