LD CAL		LOAD CALIBRATION VALUES—This parameter is used to specify
		which set of calibration values you want to use.
	FAC [factory setting]	Factory—Uses built-in calibration values (stored in read-only
		memory).
	FLD	Field—Uses calibration values stored as a result of the field
		calibration procedure described in Section 5.

			ATTENTION	Until field calibration has been done,
				Until field calibration has been done,
		FLD uses the same calibration values as FAC. When field
		calibration is performed, the value of LD CAL is automatically set to
		FLD at the completion of the field calibration operation.

INP HI	–999 to 9999	INPUT HIGH RANGE VALUE in engineering units is displayed but
	[factory setting = 900]	can only be configured for linear input type.
	[factory setting = 900]	Otherwise, this is a read-only display of the higher range value for

		the selected T/C or RTD input type.
		• Scale the input signal to the display value you want for 100 %.
		• EXAMPLE:
			Actuation (Input) = 4 to 20 mA
			Process Variable = Flow
			Range of Flow = 0 to 250 Gal/Min
			High Range display value = 250
			Then 20 mA = 250 Gal/Min

INP LO	–999 to 9999	INPUT LOW RANGE VALUE in engineering units is displayed but
	in Engineering Units	can only be configured for linear input type.
	[factory setting =	• Otherwise, this is a read-only display of the low range value for
	[factory setting =		the selected T/C or RTD input type.
	−300]		the selected T/C or RTD input type.
	−300]	• Scale the input signal to the display value you want for 0 %. See

			example in “INPHI”.

BIAS	–99.9 to 999.9	INPUT BIAS—Used to compensate the input for drift of an input
	[factory setting = 0]	value due to deterioration of a sensor, or some other cause; select
	[factory setting = 0]	the value you want on the input.

FILTER	0 to 120 seconds	FILTER FOR INPUT—A software digital filter is provided for the
	No filter = 0	input to smooth the input signal. You can configure the first order
	[factory setting = 0]	lag time constant from 1 to 120 seconds. If you do not want filtering,
	[factory setting = 0]	enter 0.
