12.4.2.6 Computing results
On the Results window, settings calculated by the auto setting for each Profiler™
are displayed.
To put this setting in the library, tick the box near each setting.
A In black, the tolerances calculated by the auto setting.
B In yellow, the profile minimum and maximum measured during the recording.
C For each algorithm, the limits calculated by the auto setting.
D
For each algorithm, the minimum and the maximum calculated during the recording.
E When algorithm limits do not include all results, the window is colored in red. If
you want, you can change it.
To select all settings click on
Select All
button.
To unselect all settings already ticked, click on
Clear All
button.
How tolerances are calculated
For each point of the
profile, the sigma is
calculated. the toler-
ance point are calcu-
lated with the
following statistical
formula:
Average +/- X sigma
By default X = 3 to enlarge tolerances (This value can be changed in the .ini file.
If this value increased, tolerances are larger).
The same principle is apply to calculate the limit of the
Expert mode
algorithm.

F Click on the button near the profile to zoom on it.
Tolerances (
A), in black, are calculated by statistic.
You can move tolerances manually to include minimum and maximum profiles (If
you are absolutely sure that all your lead/joint are good).
In the window belove, save the library on the disk, either with a same name, or with
an other name.
