Fast. Torque + Angle is a tightening strategy used in production line. Operator must set 
nominal angle, tolerances and the torque window (min, max e nominal torque).After getting a 
specific torque ( angle threshold, must be set in the test strategy), user must continue to tighten 
getting windows tolerance angle. Freedom³ will give as a main results for the statistic the angle 
and torque values  and it will show both graphs.  Also FREEDOM³ will check if the torque value at 
the pick angle is in the torque-window if not the tightening status will be not ok (NOK).

Fast. Yield is tightening strategy used in production line. Operator must set nominal torque  
and nominal angle with both tolerances. During the tightening when the joint gets the yield point, 
Freedom³ will collect as results torque and angle values at yield point and it will show both 
statistic graphs. If the torque or angle values are outside from tolerance windows, the tightening 
status will be Not OK (NOK).  
 
 
 
See below to program Freedom³ for “Fast. Yield” tightening strategy: 
 
Note: Yield.Det.Ang is an angle parameter, for default is 3°, that means Freedom³ check every 3° 
the gradient of the curve to recognize the Yield point. If the joint is more soft, we suggest to 
increase Yield.Det.Ang . The Angle value at Yield Point is the angle between  “Start torque” and 
“Yield point”.

Fast. Yield + angle is a tightening strategy used in production line. Operator must set 
nominal torque  and nominal angle with both tolerances. During the tightening, when the joint 
gets the yield point, user must over tighten the joint till arrive to the angle tolerance set in the 
test. Freedom³ will collect as results torque and angle values at pick point and it will show both 
statistic graphs. If the torque or angle values are outside from tolerance windows, the tightening 
status will be Not OK (NOK).

Yield.Det.Ang . 
The Angle value at Yield Point is the angle between  “Start torque” and “Yield point”

Test Field Table Description  
 
 
 
In the table below is explained the mining of all fields to fill, in order to run tests with Freedom³. 
Touch the correspondent screen button to enable the field:  
 
 
Field Meaning 
Description This field is used to describe the test in order to 
easily identify it. 
Test Type Is the test to run, there are different typologies 
of test: quality , SPC, Production See previous 
paragraph for the meaning of every test or 
tightening strategy. 
Nom.-Min.-Max Torque In those fields, user must write nominal torque 
and tolerances (upper and lower limits) 
Start Torque/ Angle Threshold =t’s the starting torque test, FREEDOM

Field Meaning 
Tool (Tool Extra Lenght. – Tool ACC) Torque Coefficient is a correction factor used 
when an extension  is mounted on the wrench 
and it modifies the original length used to 
certify and calibrate the wrench (let “0” if there 
is not any extension).  
Tool Angle Correction Coefficient is a 
parameter used when an long extension is 
mounted on wrench or rotary transducer, to 
compensate the torsion of extension, 
otherwise it will introduce an error in the angle 
reading. (let “0” if there is not any extension).  
Timeouts (Long T. out – Short T.out) Long Timeout is  max time allowed between 
two steps to perform the tightening  see 
paragraph… for more details. 
Short Time out is the acquisition time after the 
torque, during  tightening, exceeds 75% of 
nominal torque and go back to zero.

Freedom³ is waiting for starting  test. Selecting “Brk Test” user has to over-tightening as much as 
necessary, at the end of over-tightening, if the result is “OK” Freedom³ will display: 
 
 
 
 
 
 
 
In case of test not OK:

If the result value are outside from tolerances, Freedom³ will ask to confirm the result or to repeat 
the test (it’s possible to disable this function by setup, see “Setup LAB mode” paragraph). There is 
not limit, user can have all test he wants (Free Test), there is not any group to complete like in SPC 
test. 
 
Press “ESC” when the test is finish and FREEDOM³ will go back to Free Test page. To see Curves 
and result, once selected the test, press the right arrow on the keyboard, then press “V” on the 
sample to see.  
 
 
 
 
Freedom³ shows all test already made with the selected test:

It will appear a new window where is possible select Curves (torque/time or torque/angle) or 
value chart. See fig. below: 
 
 
 
 
 
->Selecting “Curve Torque/Time” and pressing confirm(“V” on Freedom³ keyboard), Freedom³ will 
display Torque/Time curve: 
 
 
 
 
 
By left and right arrows of Freedom³ keyboard is possible to move the cursor and analyze the 
curve step by step.
