±
99°F/±
55°C.
The default is
0°.
Appears when Ot2
=
CL.
Alarm Low: Represents the low process alarm or low deviation alarm.
Displayed only when 0t2 parameter is AL.
Alarm High: Represents the high process alarm or high deviation
alarm. Displayed only when Ot2 parameter is AL.
Calibration Offset. The range is
±99°F/±55°C.
The default is
0°.
Calibration Offset adds or subtracts degrees from the input signal.
Auto-Tune. The range of this parameter is

Local-Remote: Selects a local or remote set point for the Series
980/985.
Local set point is adjustable directly from the
980/985,
while remote can only
be changed from an external device. The signal must be within
O-5V
or
4-
20mA process input. This parameter appears if the LOC parameter
=
0, 1 or 2,
and rSP
=
0-5 or 420.
If L-r
=
r,
the remote set point is displayed in place of the
internal set point.
