CAL_POINT_LO/
LOW SENSOR TRIM
Entry
Index: 17
Data type: Float
Access: OOS
Enter the lower point of the response curve during sensor recalibration.
You can use this parameter to 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 response curve. Position adjustment must
be carried out on the device following sensor recalibration.
!
Note!
• Using the "Low Sensor Trim" method in the Pressure Transducer Block, you can carry out
dialog-guided sensor recalibration of the lower point of the response curve.
• Sensor recalibration can be reset by means of the RESET_INPUT_VALUE/ENTER RESET
CODE parameter (→ Page 64) with the code "2509".
• The PRESSURE_1_LOWER_CAL_MEASURED/LO TRIM MEASURED parameter
(→ Page 39) displays the pressure value that was present at the device during the
calibration and was used for calibrating the lower point of the response curve.
• For calibrating the upper point of the response curve, see parameter description for
CAL_POINT_HI/HIGH SENSOR TRIM.
Factory setting: lower measuring limit (→ SENSOR_RANGE, EU_0 element)

SENSOR_RANGE
Display
Index: 21
Data type: DS-68
Access: Read only
The SENSOR_RANGE parameter is a structured parameter consisting of four elements.
EU_100
• Displays the upper measuring limit of the sensor.
EU_0
• Displays the lower measuring limit of the sensor.
UNITS_INDEX
• Displays the unit selected.
DECIMAL
• Displays the number of places after the decimal point.
