  - to delete the link to the joint: tap the Delete icon () near the joint box.

  If the joint is linked to the inspection, the Target torque and Target angle are the values defined in the joint configuration.

  If the joint is not linked to the inspection, type the torque and angle values in the respective pages.

- Subgroup size: type the number of results on which the statistics are calculated. The subgroup size ranges from 1 to 25.

- Subgroup frequency: type the frequency of the averages displayed in the X chart and in the SPC rules.

  For example:

  - Subgroup Frequency = 1: all subgroups are considered.

  - Subgroup Frequency = 2: one subgroup every 2 subgroups is considered.

  - Subgroup Frequency = X: one subgroup every X subgroups is considered

- Number of samples: type the number of results to do.

  The value can range from 0 to 1000. If the number of sample is not defined or equal to 0, the test is run with no batch count.

- Auto restart: select the checkbox to enable the automatic restart of the batch count when it is completed.

- Measurement device type: the only available measuring device is the IRC-Connect.

- Measurement device S/N: type the serial number of the measuring device connected to the device.

- Transducer S/N: type the serial number of the transducer linked to the measuring device connected to the device.

- Filter frequency: type the value of the filter frequency. The allowed range is from 100 to 2000 Hz. The default value is 500 Hz.

- Tightening direction: from the drop down list select the tightening direction. The available items are:

  - Clockwise

  - Counterclockwise

Torque category

Below is a list of all the torque parameters available for the SPC inspection.

The parameters displayed by the device in the Torque category of each SPC inspection change according to the Tool type and Strategy selected.

- Cycle complete: the default value is managed by the measuring device and it is indicated as Automatic value.

  It is possible to type the cycle complete value; it must be lower/equal to the cycle start.

- Cycle start: the default value is managed by the measuring device and it is indicated as Automatic value.

  It is possible to type the cycle start value; it must be higher than the transducer Minimum Load and lower/equal to the Final angle monitoring torque.

  If the Cycle start is set to zero, the device gives automatically a Cycle Start equal to the transducer Minimum Load.

- Final angle monitoring torque: the default value is managed by the measuring device and it is indicated as Automatic value and corresponds to the lowest value between [50% of the target torque] and the [minimum torque].

  It is possible to type the final angle monitoring torque value; it must be lower/equal to the Minimum torque.

  If a Joint is linked to the inspection, this is an unavailable value equal to the Final angle monitoring torque defined in the Joint configuration.

- Control mode: select how to define the torque limits. The available options are:

  - Min/Max

  - Target/tolerance

- Minimum torque: type the value of the minimum value of the torque.

  If a Joint is linked to the inspection, this is an unavailable value equal to the minimum torque defined in the Joint configuration.

- Target torque: type the value of the target torque. This parameter is available if the Control mode is set to Target/Tolerance.

  If a Joint is linked to the inspection, this is an unavailable value equal to the Target torque defined in the Joint configuration.

- Maximum torque: type the value of the maximum value of the torque.

  If a Joint is linked to the inspection, this is an unavailable value equal to the Maximum torque defined in the Joint configuration.

- Torque tolerance: type the value of the tolerance of the torque. This parameter is available if the Control mode is set to Target/Tolerance.

  If a Joint is linked to the inspection, this is an unavailable value equal to the Torque tolerance defined in the Joint configuration.

- Measure torque at: from the drop down list, select one of the following options:

  - Torque peak

  - Angle peak

- Slip torque: the default value is managed by the device and it is indicated as Automatic value. It is possible to type a value of the slip torque smaller/equal to the Target torque.

- Unit of measurement: select the unit of measurement to use.

  If a Joint is linked to the inspection, this is an unavailable value equal to the Unit of measurement selected in the Joint configuration.

Angle category

Below is a list of all the angle parameters available for the SPC inspection.

The parameters displayed by the device in the Time category of each SPC inspection change according to the Check type selected.

This category is not displayed only for the Pulse tools.

- Control mode: select how to define the angle limits. The available options are:

  - Min/Max

  - Target/tolerance

- Minimum angle: type the minimum value of the angle.

  If a Joint is linked to the inspection, this is an unavailable value set to the Minimum angle defined in the Joint configuration.

- Target angle: type the value of target angle. This parameter is available if the Control mode is set to Target/Tolerance

  If a Joint is linked to the inspection, this is an unavailable value set to the Target angle defined in the Joint configuration.

- Maximum angle: type the maximum value of the angle.

  If a Joint is linked to the inspection, this is an unavailable value set to the Maximum angle defined in the Joint configuration.

- Angle tolerance: type the value of the tolerance of the angle. This parameter is available if the Control mode is set to Target/Tolerance.

  If a Joint is linked to the inspection, this is an unavailable value set to the Angle tolerance defined in the Joint configuration.

Time category

Below is a list of all the time parameters available for the SPC inspection.

The parameters displayed by the device in the Torque category of each SPC inspection change according to the Tool type and Strategy selected.

- Measure delay time: type the value of the measure delay time.

  During the measure delay time the torque trace is not analyzed and the click-point is not detected.

  The measure delay time ranges from 0.0 s to 5.0 s.

- Reset time: type the value of the reset time.

  During the reset time, the torque trace is not analyzed.

  The reset time ranges from 0.0 s to 5.0 s.

- End cycle time: type the value of the end cycle time.

  The “quick programming” test stops when the torque continues to be applied but it is under the Cycle complete for a time longer than the End cycle time.

  The end cycle time ranges from 0.1 s to 5.0 s.

Pulse category

This category is displayed only for the Pulse tools.

- Minimum pulse: minimum number of pulses to be done by the tool during the test.

- Maximum pulse: maximum number of pulses to be done by the tool during the test.
