Loose Torque Test 
=t’s a Quality Control test, selecting this test Freedom³ will consider as result the torque value for 
loosening of joint for a specific angle. 
The goal of this test is to see the torque necessary to unscrew a joint. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
To fill all fields see the table “field and meaning”. 
Loose Angle (°)  =t’s the angle (measured from the wrench min-load) where Freedom³  will 
collect the torque result....

Edit and Link Tightening Strategy to Locations 
 
 
By SQnet is possible to link  one tightening strategy to every single location, in order to upload to 
SQnet production tightening test results and status. 
In this paragraph we explain how to edit and link tightening strategy to a location, step by step: 
 
 
- From “Test Definition” window, select the location (operation) where you wants to link 
the tightening strategy, then select “Production” tab  Click on the bottom....

Class  In this combo box is possible to select tolerance 
classes for the tightening strategy. If user wants 
to create a new one, click on “+”and a new 
window will appear, fill all fields and press 
“confirm” to save it. 
Min and Max Angle =f user doesn’t want to define tolerance limits 
by Class combo box, also it’s possible to insert 
upper (max) and lower (min) limits manually 
writing the values in both fields.

Fields Meaning 
Un-Tightening Angle This is a negative angle parameter(Counter 
Clock wise Angle). Available only for PRW 
firmware version. Freedom³ realizes that joint 
is un-tightened only if, during the 
“unscrewing”, once overtake the open start 
cycle, the angle read at the end of Un-
tightening is higher than 1.5°. The angle written 
in this field, indicates after how many degree   
the short time-out  will be enabled. See 
paragraph….. for more info

Tightening Strategies 
 
 
 
 
 
Torque + Angle 
 
Selecting this strategy in “General data” tab of “Freedom wrenches Tightening program 
definition”, user has to tighten the joint, reaching a specific torque “Threshold”, Freedom³ starts 
to count the angle, user must continue to tighten up to getting the nominal Angle value (user can 
understand easily when is getting the nominal value watching the display or the 2 rows of led on 
the long sides of the  electronic/display case). The result...

Yield 
 
 
 
Selecting this strategy in “General data” tab of “Freedom wrenches Tightening program 
definition”, Freedom³ will detect automatically the yield point, advising by sound and vibration the 
user and showing on the display Torque and angle value at Yield point. In practice, User has to 
tighten the joint till the wrench will  recognize  the Yield point. In case the Yiled point is not 
recognized, Freedom³ will display an error message.  The Angle value at Yield point is counted...
