Setup Quick Guide
When using the Tensor Pulse strategy shown here, the tool will calculate and install dynamic torque.
The Residual Torque Correlation Factor (RTCF) is used to translate installed dynamic torque to static torque. During the setup of parameter settings the torque installed may be higher or lower than presented on the POWER FOCUS display screen. The RTCF affects the presented value, make sure to check the residual torque with an ST Wrench or similar if the joint settings are done with parts in ongoing production.
Start with setting the default parameters

Settings that use 4-8 pulses to install the torque will give the best mix of accuracy, speed, and ergonomic.
Always do the settings on the intended joint.
Reusing the same joint for many tightenings may affect the result.
Adjusting the run down speed
Choose the hardest joint in the batch and set the target torque to the specific torque required.
Tighten the joint with standard POWER FOCUS settings.
Check the torque and the number of pulses.
If needed, decrease the run down speed down to 800-1200 rpm to achieve at least 4 pulses.
Adjusting the pulse energy
Choose the softest joint in the batch and set the target torque to the specified torque required.
Tighten the joint with standard POWER FOCUS settings with adjusted run down speed.
Check the torque and the number of pulses.
Increase pulse energy up to 100% to achieve maximum 8 pulses.
Adjusting the RTCF
Choose a joint in the batch and set the target torque to the specified torque required.
Tighten the joint with standard POWER FOCUS settings with adjusted run down speed and pulse energy.
Use an ST Wrench or similar to check the residual torque.
Do a number of tightenings to check and change the RTCF, see Power Focus 6000 Configuration manual. The torque shown on the POWER FOCUS should match the torque shown on the ST Wrench.
Tighten a number of joints with the new RTCF to see if required results are met. If the tool does not perform as intended, redo steps 2 through 4 to fine tune the setup.
Tighten as many joints as needed to check the tool capability on the intended joint.
