## Perform Open End tuning

The Open End tuning function is available for tools configured with Open End Gear Front Attachment (GFA). The function calculates the true gear ratio of both the tool and the extension combined, and saves it to the tool. The tuning will take approximately two minutes to perform.

When the Open End tuning is completed the tool must be calibrated with the Open End extension attached.

1. Select Perform and then press the trigger on the tool.

2. Follow the instructions on the screen and keep pressing the tool trigger until the Open End tuning is completed.

   - If the Open End tuning was successful an OK event will be displayed.

   - If the Open End tuning was not successful, or the tool trigger was released before the tuning was finished, an NOK event will be displayed.
