5.4 CREATING CALIBRATION REFERENCES
Calibration references can be created in three ways:
-Generate
-Calculate
-Extract
Click on Reference drop down menu or appropriate icon to start this procedure.
To generate calibration file, select tight and loose wedge and perform operations described
in chapter 5.1.3 GENERATING A CALIBRATION REFERENCE.
To calculate calibration reference from an existing measurement file click on the icon
Calculate Reference. Using this operation, the software will select five tight and five loose
wedges from that measurement file. A calibration file will be created in the calibration sub-
directory with the file extension .scl, using the same file name as the measurement file. This
calibration file can be used for data display in single or two files display mode. Use of this
file will provide the maximum possible resolution of Relative Tightness Index based on
acquired results. (i.e. all RTI values ranging from 0-100 will be used)
To extract calibration references from an existing measurement file click on icon Extract
Reference. The following dialog box will appear. Select appropriate option and click on
Next.
