52 Lower Limit Indicates the lower limit (LRL) for the pressure. --- R

53 PV Range Sets the measurement range.

1. EU at 100% : Indicates input value of the upper

limit.

2. EU at 0% : Indicates input value of the lower limit.

3. Units Index : Indicates the units of the

measurement range.

4. Decimal : Indicates the digit number below the

decimal point.

EU at 100%

= 100

EU at 0%

= 0

Units Index

= kPa (1133)

Decimal

= 2

54 Linearization Type Select either No Linearization or Square root as a

setting of the output range.

0 = No Linearization :

Provides an output value scaled according to the

PV Range and Scale range settings.

(To use Direct with FF, set the same value for PV

Range and Scale.)

10 = Square root :

Provides a square root output computed for the

value scaled according to the PV Range and Scale

range settings.

0 W

55 Flow Constant Indicates the ow coefcient, which shows the

correlation between the ow rate value and square root

value of the differential pressure.

1.0 W

56 Lower Cutoff Species the low cut value. The unit is subject to

Scale.Units Index.

10 W

57 Cal Cmd Species the calibration method.

0 = CAL_NONE : Initial state in which calibration is

not performed

1 = CAL_LOW : Applies an actual input and adjusts

the lower limit using the value specied in

Calibration Lowest Point.

2 = CAL_HIGH : Applies an actual input and adjusts

the higher limit using the value specied in

Calibration Highest Point.

5 = CAL_CLEAR : Clears the adjustment variable.

0 (reading

value is

always 0)

58 Cal Status Indicates the calibration status.

0 = CAL_NONE : Start-up and default value

1 = CAL_SUCCESS : Indicates that calibration was

successful.

7 = CAL_BAD_TRIM_POINT : Indicates this status

when the adjustment variable is outside of range.

--- R

59 Calibration Highest

Point

Species the higher limit adjustment variable for

adjustment between two points.

--- W

60 Calibration Lowest

Point

Species the lower limit adjustment variable for the

adjustment between two points.

--- W

61 Calibration

Minimum Span

Indicates the minimum span of the adjustment

variable.

--- R

104 External Zero Trim Allows performing external zero adjustment.

(Trim on, Trim off)

Trim on W

105 Low Cut Mode Species the low cut mode.

(Linear, Zero)

Linear W

106 H/L Swap Allows performing reverse connection of the impulse

line.

(NORMAL, REVERSE : reverse connection)

Used when the lower pressure side and higher

pressure side of the impulse line were connected

wrongly when installing the pressure transmitter.
