C Test all leads result chart:
Lead number
Status: status of lead (good/bad)
NbPtUp/Down
: number of point out of tolerances up/down for profile (
Standard mode
)
NbGradientUp/Down: number of point out of tolerances up/down for gradient
(
Standard mode)
Peak threshold: result of peak threshold algorithm (Expert mode)
Contrast: result of contrast algorithm (Expert mode)
3DAnalysis: result of 3D analysis (Expert mode)
Profiler™ can
be defined in
the length-
ways or width-
ways of the
leads
To measure a profile, a transition on the Profiler
™
area must be detected.
If there are no transition in the profile area, the Profiler
™
is not found. You can
determine if a profile not found is good or not.

7.9.2.2 Reference profile creation
In Create Profile tab, enter the differente values of the profile to create.
1.
Define the position, the size and the orientation of the Profil-
er™. On the image, the Profiler
™
area appears in orange.
2. Define the light level.
3. In Align position on area, define the realignment op-
tion:
Select
Adjust side position to realign the profile with the side of the lead,
Select
Adjust perpendicular position to realign the profile with the end of lead,
Select
Set position on CAD position to place the profile on the CAD coordinates.
4. Choose a good lead and press the Test pin button to see the profile.
5. Click on Set Profile button to learn the profile reference.
The Profiler
™
can be placed on lead or on
joint, where there is a maximum of difference
between good leads and bad leads.
Profile become blue when you learn it. It became the reference for the Global
tolerance tool.
