Enter the upper point of the sensor characteristic curve in the event of sensor
recalibration.
By means of this parameter, you can assign a new target pressure value to a reference
pressure present at the device. The pressure value present and the target pressure
value specified for this parameter correspond to the upper point in the sensor
characteristic curve. Position adjustment has to be performed again for the device
following sensor recalibration.
• The sensor recalibration can be reset via the Reset/RESET_INPUT_VALUE
( ä 207) parameter with the "2509" code.
• Hi trim measured/PRESSURE_1_UPPER_CAL_MEASURED ( ä 184) displays the
pressure that was present at the device during calibration and was used for the
calibration of the upper point of the sensor characteristic curve.
• For calibrating the lower point of the sensor characteristic curve, see the Lo trim
sensor/CAL_POINT_LO parameter description.
Factory setting: High sensor limit (Sensor range/SENSOR_RANGE, EU_100

Enter the lower point of the sensor characteristic curve in the event of sensor
recalibration.
By means of this parameter, you can assign a new target pressure value to a reference
pressure present at the device. The pressure value present and the target pressure
value specified for this parameter correspond to the lower point in the sensor
characteristic curve. Position adjustment has to be performed again for the device
following sensor recalibration.
• The sensor recalibration can be reset via the Reset/RESET_INPUT_VALUE
( ä 178) parameter with the "2509" code.
• The Lo trim measured/PRESSURE_1_LOWER_CAL_MEASURED ( ä 184)
parameter displays the pressure that was present at the device during calibration
and was used for the calibration of the lower point of the sensor characteristic
curve.
• For calibrating the upper point of the sensor characteristic curve, see Hi Trim
