Try using crimp height instead of pull test if you are getting "off"
results... Look up amp/tyco's application spec for "Screw Machine Contacts"
and you 'll find AF8 (M22520/1-01) crimp height.
As far as tool setting, ... uh... what brand of crimps are you using, and
are they Military contacts?
Keep us posted...

Juan,
Two wires in a pin designed for a single wire pin such as the crimp that
uses the 4 indents, e.g. Daniels AF-8, is not a way to go. Whenever I see
this situation in designs I ask for a splice upstream so that I can crimp a
single wire into a contact. Crimp splices are acceptable as well as the use
of solder sleeves.
I ask for this because of the scenario that you presented. It is difficult
to get a accurate pull test reading. It is also difficult to determine the
proper tool setting.
Good luck.
