Retransmit Output 3 Scale Minimum
Defines the value of the process variable, or setpoint, at which Retransmit Output 3 will be at
its minimum value. It is similar to Retransmit Output 1 Scale Minimum.
Display code = 9"4+ , default value = Scale Range Lower Limit.
Also refer to Process Variable, Retransmit Output, Retransmit Output 3 Scale Maximum,
Scale Range Lower Limit and Setpoint.

Scale Range Upper Limit

For linear inputs, this parameter is used to scale the process variable into engineering units.
It defines the displayed value when the process variable input is at its maximum value. It is
adjustable from -1999 to 9999 and can be set to a value less than (but not within 100 units
of) the Scale Range Lower Limit, in which case the sense of the input is reversed.
For thermocouple and RTD inputs, this parameter is used to reduce the effective range of the
input. All span related functions work from the trimmed input span. The parameter can be
adjusted within the limits of the range selected by Configuration Mode parameter <%1# . It is
adjustable to within 100 degrees of the Scale Range Lower Limit.
Display code = 9>+ , default value = 1000 for linear inputs or range maximum for temperature
inputs.
Also refer to Input Span, Process Variable and Scale Range Lower Limit.

Scale Range Lower Limit

For linear inputs, this parameter can be used to display the process variable in engineering
units. It defines the displayed value when the process variable input is at its minimum value.
It is adjustable from -1999 to 9999 and can be set to a value more than (but not within 100
units of) the Scale Range Upper Limit, in which case the sense of the input is reversed.
For thermocouple and RTD inputs, this parameter is used to reduce the effective range of the
input. All span related functions, work from the trimmed span. The parameter can be
adjusted within the limits of the range selected by Configuration Mode parameter <%1# . It is
adjustable to within 100 degrees of the Scale Range Upper Limit.
Display code = 9>+ , default value = 0 for linear inputs, or range minimum for temperature
inputs.
Also refer to Input Span, Process Variable and Scale Range Upper Limit.

Secondary Proportional Band

The portion of the input span over which the Secondary Output power level is proportional to
the process variable value. It may be adjusted in the range 0.0% (ON/OFF) to 999.9%.
Display value = -6B: , default value = 5.0%.

and Tuning.
