If the lead does no longer stand out well from the background, in the case of white plugs, for ex-
ample, use this option to specify the number of leads to be measured. However, to do this, the
component must be fully described in the line computer (FDC). In this case, there are no further
lead measuring steps.
NOTE
This value should only be modified for special components and plugs.
