Matching Link Elements with a Reference
Matching Link Elements with a Reference
When any measurement is selected as reference measurement, all
elements of the reference measurement are considered as reference
elements. The application uses an algorithm with tolerance to match these
elements. For more information of setting the tolerance, see Modifying
iOLM Settings (FR2-FC Mode) on page 219.
Note: If you have selected a reference measurement, the link length displayed is
that of the reference measurement.
To set a reference measurement:
In the Elements Table tab, right-click on the measurement that you want to
use as the reference, then select Set as Reference. The measurement
changes color in the table to indicate its new status and the corresponding
row is blocked at the top of the table so that you always see it even when
scrolling down the list of other measurements.
