5. CONFIGURATION
Pressure Raw Value Unit:
This contains the pressure unit for the calibration
values.
Pressure Raw Value:
This contains the calibrated sensor value. The unit is
derived from pressure raw value unit.
Sensor Upper/Lower Limit:
These contain the sensor upper/lower limit value. The
unit is derived from pressure raw value unit.
Upper/Lower Calibration Point:
These contain the highest/lowest calibrated value. For
calibration of the high/low limit point give the high/
low measurement value (pressure) to the sensor and
transfer this point as HIGH /LOW to the transmitter.
The unit is derived from pressure raw value unit.
Pressure Unit:
This contains the pressure unit of the pressure value.
The following units are available for the EJA.

Pressure Value:
This contains the pressure value and status available to
the function block.
Measuring Range (Scale In):
This is the input conversion of pressure into a % value
using the upper and lower scale. The related unit is the
pressure unit.
Characterization Type:
This sets the linearization type: Linear or Square root.
If set to “Square root”, the square root is extracted and
the value is reflected in the measured value. "Linear" is
the factory default.
Low Flow Cut off:
This is the flow percentage at which the output of the
flow function is set to zero.It is used for suppressing
low flow values.
Measured Value:
This is the transducer block output and input to Analog
Input1.
Temperature Unit:
This contains the units of the sensor temperature.
Sensor Temperature:
This contains the sensor (capsule) temperature (e.g.
sensor temperature used for measurement compensa-
tion). The related unit is the temperature unit.
Static Pressure Unit:
This parameter contains the units of the static pressure.
Static Pressure:
This parameter contains the static pressure. The related
unit is the static pressure unit.
Trim PV Zero, Extenal Zero Enable:
This is for zero-point adjustment. There are two
methods for adjustment, (1) using the external zero-
point adjustment screw, and (2) using the parameter of
the transducer block.
Display Mode, Display Cycle:
This sets the unit to be used for LCD display and the
cycle of LCD display. If a low temperature environ-
ment makes it difficult to view the display, it is
recommended that you set a longer display cycle.
