# Synchronized Tightening Results

The tightening results are displayed in a condensed list that can be individually or collectively chosen for further analysis.

For each controller, a maximum of 1024 latest received results can be stored in the ToolsTalk database. When the controller is offline, the results occurring during this time will not be transferred to ToolsTalk when the controller returns online.

Select Show only NOK results at the bottom of each page to only view the results with NOK status.

On the top level the result for a synchronized tightening with several channels contain the following information:

Tightening result

GUI part | Description
--- | ---
Red bar | The leftmost position in the Live results table may contain a red bar icon. This is shown together with erroneous tightenings for quick identification of errors. This corresponds to NOK.
Holding pin | Select the holding pin icon to pin the result to the pinned tab.
Trace icon | Select the trace icon to view a graphical view of the results in the Trace workspace.

Channel result

For each channel an overall result is reported with the following content:

GUI part | Description

Final Angle | The actual measured angle of the last tightening step It is the Step Monitor Peak Angle located in the last tightening step that reports this parameter.
Final Torque | Final Torque for the tightening. It is the Step Monitor Peak Torque located in the last tightening step that reports this Parameter.
Target torque | Target torque.
Elapsed time | Time from tightening start to end.
Mode | Mode Name/Number
Shunt calibration | Select this icon to display the shunt calibration data.

Step results

Each step in the multistep tightening program reports data. Most of this data is coming from the monitors and restrictions that are active during the step, so the data is only reported if a monitor or restriction of the correct type is configured.

The same step may be executed more than once if repairs are made.

Result Parameter | Description
--- | ---
Step number | The number of the step.
Status | Status of the step, OK or NOK.
Step type | Step type in the multistep program.
Path | Indicates where in the program the step is located, that is, if it is in the tightening path, a repair, or a termination path.
Peak Torque | Measured final torque including the torque induced during the internal break. Typically the peak torque is higher than the shut-off torque.
Elapsed time | Time from tightening start to end.
Angle | Displays the angle
Click Torque | Displays the Click Torque
Click Angle | Displays the Click Angle

## Result Reporter

The list shows the values from the result reporters. If there is a result reporter defined for a program monitor/restriction, the value from that monitor/restriction is reported. If there is no result reporter defined for a program monitor/restriction, the value from the latest executed step in main path with a reporter is reported.

## Trace

On a result click on the Trace icon if it is active. . The result graph is displayed. It is possible to view several traces simultaneously by selecting several traces.

The Trace workspace shows detailed graphical information on one or several tightening result.

On the workspace, use the mouse wheel to zoom in or zoom out. Or you can select an area to zoom in. Double click the trace area to go back.

Examples:

Select an area to zoom in:

To move the trace, press the wheel button of the mouse:

In the trace graph, delta information based on the selected axis types can be displayed. Right-click the two points you want to compare to show the delta between them. Drag the point to modify the target.

Drag the delta to move it or press Delete to delete it.

Trace settings | Description
--- | ---
Limits | Check this box to If one curve is shown, limit values can be shown if they are used in the tightening program.
Gridlines | Check this box to show the gridlines in the result graph.
Min/Max | Show minimum or maximum measured value.
|X-Axis| | Show the absolute value for X-axis.
Y1 | Choose the information to be shown in the Y1-axis: Torque Angle Speed Current Gradient
Y2 | Choose the information to be shown in the Y2-axis: None Torque Angle Speed Current Gradient
Y3 | Choose the information to be shown in the Y3-axis: None Torque Angle Speed Current Gradient
X | Choose which information to be shown X-axis: Time Angle

Traces can be synchronized by X-axis offset with different options. Trace synchronization is available when there are two or more trace results selected.

Sync Options | Description
--- | ---
None | No offset is set to any trace
Manual | (Only available when there are two trace results selected) Synchronize the traces to any synchronization point by manually dragging the lower scale of the X-axis.
Peak | Synchronizes the traces by their absolute peak values.
Set Value | Synchronizes the traces by a specific value: Torque: Offset all traces so that the angles or times of the first time the traces reaches this torque value coincide. Angle: Offset all traces so that the angles or times of the first time the traces reaches this angle value coincide. Speed: Offset all traces so that the angles or times of the first time the traces reaches this speed value coincide. Current: Offset all traces so that the angles or times of the first time the traces reaches this current value coincide. Gradient: Offset all traces so that the angles or times of the first time the traces reaches this gradient value coincide.
Measurement Point | Synchronizes the traces by a specific measurement point: Rundown Complete (CATLA) First Target (CATLA)

Buttons | Description
--- | ---
Remove all Δ | Remove all the deltas.
Export... | Exports the trace chart view to the following targets: JPEG / PNG image System printer
Remove all | This button clears the trace plot area.

Latest results tab

Displays the results for the latest tightenings.

Search Results tab

Use the Search button to search for results between specific dates.

Pinned tab for investigation

A tightening result can temporarily be stored into the Pinned tab. This is useful for detailed analysis of a tightening, and prevents the tightening result to be dropped from the window as new results are received.

Live results tab

A controller sends tightening results to ToolsTalk 2 as soon as the task is completed, and the result is added to the top of the Live results. A limited number of results can be stored. When the list is full, the oldest result is dropped from the list.

Imported tab

For viewing imported results.

## Shunt Calibration

Shunt calibration is an electrical check of a transducer. The transducer is checked for offset and shunt calibration at the start of each cycle. Shunt calibration limits can be adjusted.

In ToolsTalk 2, the limits can be seen—but not changed—in Plant structure > Tools. Select a tool that can display offset and shunt-calibration values in the Zero Offset and Shunt Limits section.

To change offset and shunt values, access the tool display from a web browser. For more information, see the user guide or product information for the tool.

The shunt calibration results in different metrics:

Parameter | Unit | Description
--- | --- | ---
Multistep Name | [text field] |
Gain | Nm | Measured value from a shunt calibration test.
Gain Difference | Nm | The change in the measured gain value since the last test.
Gain Limit High | Nm | The limits for the measured gain to be acceptable.
Gain Limit Low | Nm | The limits for the measured gain to be acceptable.
Gain Max Change | Nm | The limit for the gain difference to be acceptable.
Offset | Nm | The measured zero offset, the torque reading at rest.
Offset Difference | Nm | The change in the measured offset value since the last test.
Offset Limit High | Nm | The limits for the measured offset to be acceptable.
Offset Limit Low | Nm | The limits for the measured offset to be acceptable.
Offset Max Change | Nm | The limit for the offset difference to be acceptable.
Shunt Failed | True or false | The value is true if the gain or gain difference is outside of limits.
Zero Offset Failed | True or false | The value is true if the offset or the offset difference is outside of limits.
