# Intersection

This strategy verifies that the result is the intersection point of two lines, which are drawn from the points where the trace intersects with four user-defined angle thresholds.

Parameter | Description
--- | ---
Inspection Name | Name of the inspection.
Torque correction coefficient | When extensions are used, the wrench measurement must be compensated to show a more accurate torque value. To calculate the correction coefficient, please refer toHow to calculate the Torque Correction Coefficient. When extensions are not used, Torque correction coefficient = 1.
Angle correction coefficient | When extensions cause additional wrench bending, the wrench angle measurement must be compensated to show a more accurate angle value. To calculate the correction value, please refer to How to Calculate the Angle Correction. When extensions are not used, Angle correction coefficient = 0.
Number of sample | Number of tests to run inside the inspection. Maximum value: 1000. If Number of sample = 0, the number of tests is infinite. If Number of sample > 1, batch result OK only if all tests are OK.
Cycle start | Torque value from which the test operation starts. The Cycle start must be ≤ Final angle monitoring torque value, and must be ≥ smartHEAD Min load value. If Cycle start = 0, its value is automatically set to the smartHEAD Min load value.
Minimum torque limit | Minimum torque value that must be reached within the Target angle value in order to get an OK result.
Maximum torque limit | Upper torque limit value.
Change screw | If the torque applied reaches this limit, the message Change screw is shown on the wrench display. Must be > Maximum limit torque. The Change screw must be equal or higher than the Maximum limit torque.
Target torque | Torque target value.
Torque tolerance | Tolerance that defines the maximum torque and the minimum torque according to the Target torque previously specified. Value is expressed in percentage (%).
Final angle monitoring torque | Torque value from which the angle measurement starts (usually set to 50% of the Target torque). If Final angle monitoring torque = 0, its value is automatically set Cycle start value.
Control mode | Method to define the torque limits from the following options: Min/Max: the torque lower and upper limits are the values entered for the parameters Minimum torque and Maximum torque. Target/Tolerance: the torque lower and upper limits are calculated according to the values of the parameters Target torque and Torque tolerance.
Residual angle threshold 1 | Maximum angle value (measured from the Final angle monitoring torque) for the residual torque when the residual torque is lower than the breakaway point.
Residual angle threshold 2 | Maximum angle value (measured from the Final angle monitoring torque) for the residual torque when the residual torque is lower than the breakaway point. The Residual angle threshold 2 must be higher than the Residual angle threshold 1 .
Residual angle threshold 3 | Maximum angle value (measured from the Final angle monitoring torque) for the residual torque when the residual torque is lower than the breakaway point. The Residual angle threshold 3 must be higher than the Residual angle threshold 2.
Residual angle threshold 4 | Maximum angle value (measured from the Final angle monitoring torque) for the residual torque when the residual torque is lower than the breakaway point. The Residual angle threshold 4 must be higher than the Residual angle threshold 3 .
Ratchet time | Starts when the torque goes below the Cycle start without reaching the 3rd percentage value. This allows the operator to release the torque for a while and recharge during the tightening operation. Default value: 0.1 sec. Minimum value: 0.1 sec. Maximum value: 30 sec.

T0 | Final angle monitoring torque | T1 | Minimum torque
a1 | Residual Angle Threshold 1 | a2 | Residual Angle Threshold 2
a3 | Residual Angle Threshold 3 | B | Breakaway

Results:

- If the value is between the user-defined torque range, the result is OK.

- If the last angle threshold is not reached, the result is not OK.
