# Preparing the Calibration

1. Make sure the tool and controller are set up to perform tightening.

2. Set up the tool with a torque reference transducer (such as the STa6000, STpad or JSB Bench).

   Refer to the torque reference transducer User Guide for set-up instructions.

3. Select a Tightening program with a target torque corresponding to a tightening normally used with your tool.

   See Basic Tightening setup for a tutorial on setting up and activating a suitable tightening program.
