Process Power Digital Input (36)

Enable the thermocouple short detection feature by selecting a digital
input.

Range: 0 to 8 (Disabled = 0, Enabled = 1 to 8 indicating the selected

digital input).

Default: 0.

High Reading (37)

This parameter contains one of four points used to scale inputs. For
thermocouple and RTD inputs, the high reading is expressed in tenths of
a degree Celsius or Fahrenheit. For linear inputs, the high reading value
is expressed in tenths (CLS) or hundredths (MLS) of a percent of full
scale. For pulse inputs, the high reading value is expressed in Hertz.

Range: –999 to 9999 (CLS), –9990 to 11000 (MLS).

Default: 14000 (1400°F) for a J-type thermocouple.

Low Reading (38)

This parameter contains one of four points used to scale inputs. For
thermocouple and RTD inputs, the low reading is expressed in tenths of
a degree Celsius or Fahrenheit. For linear inputs, the low reading value
is expressed in tenths (CLS) or hundredths (MLS) of a percent of full
scale. For pulse inputs, the low reading value is expressed in Hertz.

Range: –999 to 9999 (CLS), –9990 to 11000 (MLS).

Default: –3500 (–350°F) for a J-type thermocouple.

NOTE

Note: Do not change High and Low Readings if the Input
Type is NOT set to Linear or Pulse.

Heat/Cool Spread (39)

This parameter describes a deadband about the setpoint for heat/cool
loops. The heat/cool spread is in units of the input variable. This
parameter is affected by the Precision parameter.
