    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. 
    Counterclockwise only for Left Hand Joints. 
    The test result will be ok (in order) if the torque reading (at the angle specified in the settings) is in 
    the windows tolerance. 
    Note 
    To perform this test, user must to unscrew the bolt. Usually it’s necessary to move the wrench in 
    counter clockwise, then all the parameter to fill in the test table, are referred to a counter 
    clockwise movement.

    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. 
     
     
      
      
     
         
                   
     
    - Once “Production” tab is selected on the bottom part of the window will 
    appear 2 icons:

    Fields Meaning 
    Tightening Type In this combo box user must choose the right 
    strategy to use during the tightening: Torque + 
    Angle; Torque with Angle Monitoring; Torque + 
    Angle CCW; Torque with Angle monitoring 
    CCW; Yield; Yield + Angle. See next paragraph 
    for more details 
    Operation Type In this combo box user must indicate which 
    operation he has to do during the tightening: 
    tighten; loosen; Loosen and Tighten; 
    Bidirectional. 
    Station Id Here , user can write the identification number 
    of the station where the joint is located. This 
    field is not mandatory  
    Nominal Torque In this field, user must write the torque target 
    to reach during the tightening. 
    Nm (Measure Unit) Clicking on this combo box, user can change the 
    measure unit, actually the measure available 
    are: cNm; Nm; kgfm; ozf.in; kNm; lbf.ft; lbf.in 
    Class (torque) 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 Torque =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. 
    Threshold =t’s the torque value where Freedom3 starts to 
    count the angle. 
    Nominal Angle =t’s the angle target value that user has to reach 
    during the tightening.

    window will appear, fill all fields and press

    by Class combo box, also it’s possible to insert 
    upper (max) and lower (min) limits manually 
    writing the values in both fields. 
    Min Angle to Min Torque This parameters is used to inform operator 
    when he is tightening a screw already tighteneT 
    (only for PRW firmware version). User has to fill

    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   
    Long Time-Out* This parameter is in milliseconds. It is used 
    from the wrench to understand when test is 
    finished (especially when user has many 
    resumptions). When user starts to tighten and 
    the torque overtakes the min-load of his 
    transducer (usually 5% of full scale) but torque 
    doesn’t reach 75% of target torque, long time-
    out is enabled, that means all times torque 
    goes back under min-load (especially between 
    tightening steps) Freedom³ starts to count 
    time. If the time break is higher than “Long 
    Time Out”, the wrench will consider as result of 
    the test the peak reached inside 75% of Target 
    Torque. If the time break is lower than  Long 
    Time Out and torque overtakes  75% of Target 
    Torque, Long Time-Out is disabled and Short 
    Time-Out is enabled, see next point. 
    Short Time-Out* This parameter is in milliseconds. It is used 
    from the wrench to understand when test is 
    finished. When user overtakes 75% of Target 
    Torque, Short Time-Out is enabled, that means 
    all times torque goes back to zero, Freedom³ 
    starts to count time. If the time break is higher 
    than “Short Time Out”, the wrench will 
    consider as result of the test the peak reached 
    up 75% of Target Torque. 
     
    Note: 
    *The example in the description is referred to “torque” strategy tightening, the same 
    consideration are applicable to “angle” strategy tightening.

    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 will be considered “OK” if the angle and 
    torque values will be in the tolerances (inside the green window). The main parameters for 
    statistic is angle value (wrench collects all time angle and torque values). 
     
     
    Note  
    Torque + Angle CCW strategy is the same program but for left-handed joints. 
    CCW-> Counter ClockWise

    Torque with angle monitoring 
     
     
     
     
     
     
    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 Torque 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 will be considered “OK” if the torque and 
    angle values will be in the tolerances (inside the green window). The main parameters for statistic 
    is torque value (wrench collects all time angle and torque values). 
     
    Note 
    “Torque with angle monitoring CCW” is the same strategy but for left-handed joints. 
    CCW -> Counter ClockWise

    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 
    from the “Threshold” torque value. The result will be considered “OK” if the angle and torque 
    values will be in the tolerances (inside the green window). In this tightening strategy both 
    parameters torque and angle values will be considered for statistic charts (wrench collects all time 
    angle and torque values). 
     
    Note  
    This tightening strategy is available only for Fredoom³ SPC mode.
