ROUNDING INCREMENT
0 to 066
In steps of 1 least significant digit,
regardless of decimal point.
Rounding selections other than 1 cause the process value
display to round to the nearest rounding increment selected. (For
example, rounding of 5 causes 122 to round to 120 and 123 to
round to 125.) Rounding starts at the least significant digit of the
process value. Setpoint values, Setpoint limits, Alarm values,
Input Scaling values, and Analog Scaling values are not affected
by rounding.

DIGITAL FILTERING
6 = least to < = most
The filter is an adaptive digital filter that discriminates between
measurement noise and actual process changes. If the signal is
varying too greatly due to measurement noise, increase the filter
value. If the fastest controller response is needed, decrease the
filter value.

F1 KEY FUNCTION
The controller performs the selected F1 Key Function, when
! is pressed while in the Display Loop. In any other loop or
module location, pressing ! will perform an escape to the
Display Loop.
No Function: No function is performed.
Auto/Manual Select: This function toggles (momentary action)
the controller between Automatic and Manual Control.
Setpoint 1 or 2 Select: This function toggles (momentary
action) the controller between Setpoint 1 and Setpoint 2.
Reset Alarms: This function can be used to reset one or both of
the alarms when activated (momentary action) The alarm will
remain reset until the alarm condition is cleared and triggered
again.

TYPESELECTION
Select the input type that corresponds to the input signal.
SCALING
To scale the controller, two scaling points are necessary. Each
scaling point has a coordinate pair of Display Values and Input
Values. It is recommended that the two scaling points be at the
low and high ends of the input signal being measured. Process
value scaling will be linear between and continue past the
entered points to the limits of the input range. (Factory settings
example will display 0.0 at 4.00 mA input and display 100.0 at
20.00 mA input.) Reverse acting indication can be accomplished
by reversing the two signal points or the Display value points, but
not both. If both are reversed, forward (normal) acting indication
will occur. In either case, do not reverse the input wires to
change the action.
