Online/AO Meter
Displays a gauge meter representation of the current
value of the Analog Output
Online/PV AO
Displays the current value of Analog Output in mA
Online/TV
Displays the current value of the Tertiary Variable
(static pressure) in psi
Online/PV % rnge
Displays the current value of transmitter Output in %
Online/PV LRV
Displays the current value of the Lower Range Value

engineering units. This value may be configured to
any value within the range LTL to UTL.
Online/PV URV
Displays the current value of the Upper Range Value
(input which represents 100% output) in user
selected engineering units. This value may be
configured to any value within the range LTL to UTL.
Online/ PV LRL
Displays the Lower Range Limit of the transmitter in
user selected engineering units.
Online/ PV URL
Displays the Upper Range Limit of the transmitter in
user selected engineering units.
Online/ PV LTL
Displays the Lower Transducer Limit of the
transmitter in user selected engineering units.
Online/ PV UTL
Displays the Upper Transducer Limit of the
transmitter in user selected engineering units.

Pressure Transfer function:
Click the 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)

Low flow Cutoff (Sq
Root)
Low Flow Cutoff
Mode
For Square Root (Transfer function) configurations
only, choose the operating mode to determine the
low flow cutoff breakpoint:
Dual slope:
(breakpoint determined by dual
slope calculation)
User configuration:
(breakpoint defined by
user)
Low Flow Cutoff
Breakpoint
When
User Configuration
is selected for Low Flow
Cutoff Mode, enter the desired breakpoint value.
