Parameter Definition
Linear
Square Root
Input 1 High
Value
–999. To 9999.
Floating (in
engineering
units)
Input 1 High Range Value in engineering units is
displayed for all inputs but can only be
configured for linear or square root transmitter
characterization.
Scale the #1 input signal to the display value you
want for 100 %.
FOR EXAMPLE:
Process Variable = Flow Range of Flow = 0 to 250
Liters/Minute Actuation (Input 1) = 4 to 20 mA
Characterization (XMITTER) = LINEAR Set IN1 HI
display value to 250 Set IN1 LO display value to
0 Then 20 mA = 250 Liters/Minute and 4 mA = 0
Liters/Minute
ATTENTION: The control setpoint will be
limited by the range of units selected here.
Input 1 Low
Value
–999. To 9999.
Floating (in
engineering
units)
Input 1 Low Range Value in engineering units is
displayed for all inputs but can only be
configured for linear or square root transmitter
characterization. Scale the #1 input signal to the
display value you want for 0 %. See example
above.
ATTENTION: The control setpoint will be
limited by the range of units selected here.
Input 1 Ratio –20.00 to 20.00
Floats to 3
decimal places
Ratio on Input 1 —Select the Ratio value you
want on Input 1.
Input 1 Bias –999. to 9999.
(in engineering
units)
Bias on Input 1 — Bias is used to compensate
the input for drift of an input value due to
deterioration of a sensor, or some other cause.
Select the bias value you want on Input 1.
