51
Upper Limit
Indicates the upper limit (URL) for the pressure.
---
R
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.
1. EU at
100% =
25000.000000
EU at 0%
= 0
Units Index
= kPa
Decimal
= 2
W
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.)
0
W
55
Flow Constant
Indicates the flow coefficient, which shows the
correlation between the flow rate value and square root
value of the pressure.
1.0
W
56
Lower Cutoff
Specifies the low cut value. The unit is subject to
Scale.Units Index.
10
W
57
Cal Cmd
Specifies 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 specified in
Calibration Lowest Point.
2 = CAL_HIGH : Applies an actual input and adjusts
the higher limit using the value specified in
Calibration Highest Point.
5 = CAL_CLEAR : Clears the adjustment variable.
0 (reading
value is
always 0)
W
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
Specifies the higher limit adjustment variable for
adjustment between two points.
---
W
60
Calibration Lowest
Point
Specifies the lower limit adjustment variable for the
adjustment between two points.
---
W
61
Calibration
Minimum Span
Indicates the minimum span of the adjustment
variable.
108 = Gauge pressure
109 = Absolute pressure
---
R
102
Static Process
Type
Selects the gauge pressure or the absolute pressure.
Abs
W
103
SP Select
Parameter to select the High-side pressure or the Low-
side pressure as the static pressure output.
0 = High : Displays the H-side pressure as the static
pressure
1 = Low : Displays the L-side pressure as the static
pressure
