This only illuminates the % annunciator. It does not perform any type of

ROUNDING INCREMENT
1 to 1
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.

For Key-in Method, enter the first coordinate Input Value by using the arrow
keys. To allow the P16 to “learn” the signal, use the Applied Method. For Applied
Method, press L. The ° annunciator is turned on to indicate the applied method.
Adjust the applied signal level externally until the appropriate value appears
under I1. Using either method, press A to store the value for I1. (The
controller can be toggled back to the Key-in Method by pressing L before A.)
DECIMAL RESOLUTION
This selection affects the decimal point placement for the Process value, and
related parameters.

DIGITAL FILTERING
= 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.
F1In
F1 KEY FUNCTION
The controller performs the selected F1 Key Function, when L is pressed
while in the Display Loop. In any other loop or module location, pressing L
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.

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.
