Calibration Lowest Point/
CAL_POINT_LO
Entry
Index: 17
Data type: float
Access: OOS
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.
!
Note!
• The sensor recalibration can be reset via the Enter Reset Code /ENTER_RESET_CODE
parameter (→ ä 93) with the "2509" code.
• The Lo Trim Measured/LOW_TRIM_MEASURED parameter (→ ä 60) displays the
pressure value that was present at the device during calibration and was used for
calibrating the lower point of the sensor characteristic curve.
• For calibrating the upper point of the sensor characteristic curve, see the parameter
description for Calibration Highest Point/CAL_POINT_HI.
Factory setting: Low sensor limit (→ Sensor Range/SENSOR_RANGE, EU_0 element)
