SPC Quality Control  test 
(For Freedom³ and DataTouch³) 
 
 
 
SPC Production tool test 
(only for DataTouch³) 
 
 
 
 
 
 
User has to select the test to link to the location, selected the right control strategy for SPC Quality 
Control test.SPC Production Tool Test is only available for DataTouch³, for this kind of test is 
necessary to connect a rotary or static transducer with joint simulator.

Quality Control Test 
 
 
Breakaway Test  
=t’s a Quality Control test, user has to over-tightening  joint already screwed. Selecting this test 
user has to specify the strategy: peak; torque/angle; smart  breakaway (see the table “field and 
meaning” for more information). 
 
 
Test parameters 
Selecting Breakaway test, it will be appear a new window  to fill in order to set test parameters.

Fields Meaning 
Stat Group Size =t’s a minimum number of measure to create a statistic chart

Tool 
User has to fill this section only if on the wrench used for the breakaway, is added an extension 
that modifies the original length of the wrench or modifies the angle reading (long and flexible 
extension introduce an error in the torque and angle reading). 
 
 
 
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
       
 
 
 
            
Fields Meaning 
Tool nr. =t’s the id number of the extension 
Length (mm) =t’s the  length of the extension tool

Peak  
Selecting in test parameters “test type: peak” user has to fill the threshold value for this strategy. 
Example if the threshold value is 10 Nm, Freedom³ will consider as result only the peak torque 
over 10 Nm.

Torque/angle 
Selecting in test parameters “Test Type: Torque angle” user has to set “Threshold and Angle 
Detection values”. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Using this Breakaway strategy, Freedom³ will collect as result the torque value after a specific 
angle. The angle counting will start after a specific torque value “threshold”. 
For example: if the threshold value is 10 Nm and the angle value is 3°, Freedom³ will consider as 
result the torque value after 3° over 10 Nm. 
Note: 
For this strategy it’s necessary to know the behavior of the joint in order to set the corrects values 
(user has to know torque and angle parameters where breakaway point is expected, the detection 
of breakaway point is not automatic). 
This strategy allows to be sure to take every time the torque value exactly at the same point 
without operator influence. 
 
 
 
 
 
  
						

							38 
 
Smart 
Using this strategy, Freedom³ will recognize automatically the breakaway point. User has to set: 
the start torque and angle reading (Threshold); Torque Alarm is the max torque operator can 
reach (after this specific value Freedom³ will display the message “change screw”, in order to do 
not run any risk to let a broken joint after test); Angle alarm is the max angle operator can reach 
(after this value Freedom³ will display an alarm message); select “No dynamic breakaway” for first 
peak detection (For more info see paragraph Smart Breakaway test in Freedom³ LAB mode).

Loose  and Tightening Test 
=t’s a Quality Control test, selecting this test Freedom³ will consider as a result the torque value 
reached after user loose and tighten again the bolt exactly to the original position (For more info 
see paragraph Loose and Tightening test in Freedom³ LAB mode). 
 
 
  
 
 
 
To fill all fields see the table “field and meaning”. 
Loose angle (°)  In this field user has to indicate how many degree the bolt must be unscrewed. 
The test result will be OK (In Order) only if the torque value reached, after user loose and tighten 
again the bolt exactly to the original position, will be between the Min and Max Torque.

Min Torque Test 
=t’s  a Quality Control Test, selecting this test, Freedom³ will consider as result the torque value 
over-tightening a bolt already screwed for a specific angle. The goal of this test is to check if a bolt 
is tightened and to check if it’s  enough tightened  (For more info see paragraph Min Torque test in 
Freedom³ LAB mode). 
 
 
 
 
 
To fill all fields see the table “field and meaning”. 
Nominal Torque  =t’s the minimum expected torque after the bolt is over tightened for a specific 
angle. 
Check Angle (°)  =t’s the angle (measured from the wrench min-load) where Freedom³  will 
collect the torque result. 
 
The test result will be considered ok (in order), if the torque read at the specific angle is higher 
than nominal torque.
