# Viewing Synchronized Traces

Synchronizing traces older than software version 3.5 is not supported.

Synchronize and compare traces

1. On the Home view, select the Reports Tab. On the left side, Results is automatically selected.

2. In the Results window, select View all results.

3. Select the traces to compare by marking the icon of the corresponding results. A selected trace icon turns blue.

   Up to 10 traces can be selected.

   Results without the icon do not support synchronization.

4. Select the icon in the upper right hand corner, to open the sync trace view. When selecting the icon all selected result traces will be unchecked.

5. In the Sync Trace Result View, select the preferred Sync method from the drop-down list.

   Select the trace types with the arrows in the upper right hand corner.

The Sync Trace Result View is shown below:

Point and click on image to see more information:

Position | Description
--- | ---
1 | Select method to synchronize traces and display of current sync method.
2 | Switch between available trace types. The following trace graphs are available: Torque / Time Torque / Angle Angle / Time Speed / Time Speed / Angle Gradient / Time (when the tightening program is configured to make a gradient trace) Gradient / Angle (when the tightening program is configured to make a gradient trace) Current / Time Current / Angle
3 | Zoom methods to examine sections of the traces in more detail. Select "+" to zoom in , "-" to zoom out, or the "square icon" to reset the zoom level back to the default view. It is also possible to zoom to a specific section by holding down the right mouse button, moving the mouse over a section, and release the right mouse button. The area inside the drawn rectangle defines the area to show.
4 | Each result is represented by one tab, showing the time when the tightening was performed. An icon on the left of each tab reflects the outcome of the tightening: Blue: Tightening successful Red: Tightening failed Exclamation mark: The trace cannot be shown in the diagram Clicking on the icon toggles between the following display settings for its trace: Show trace only Show trace and step dividers with available limits or restrictions Hide trace
5 | Change primary result trace. The primary result trace is used as reference and will define the values for the x-axis. Only one trace can be set as primary result. The first selected trace (the left-most tab) is by default used as reference.
6 | Tightening details of currently selected result.

## Sync methods

Sync methods are different strategies to synchronize traces by a specific value.

Traces can be synchronized by, for example, peak torque (highest torque reached for each trace). This shifts all traces along the x-axis, until each curve has its peak torque value at the exact same position on the x-axis.

All subsequent results are given an offset on the x-axis according to one of the following methods:

Sync method | Description
--- | ---
None | Default value. Selected traces are not synced.
Peak / Torque Peak / Angle Peak / Speed Peak / Current Peak / Gradient | All traces are synchronized towards the peak value, that is, shifted along the x-axis so that the peak values are at the same position on the x-axis as the peak value of the primary result.
Custom / Torque Custom / Angle Custom / Speed Custom / Current Custom / Gradient | All traces are synchronized towards a set value, shifted along the x-axis so that the set value are the same at the same position The set value of the primary result is used as reference point on the x-axis. If sync method Custom is selected and none of the traces contains the configured value, an exclamation mark is shown in the custom value field.

If a result has no trace value that matches to the sync method it cannot be synchronized and its trace will not be shown. It will instead be shown with an exclamation mark.

If none of the traces are possible to synchronize, the error message “Unable to synchronize” is shown.
