10.3.2.3 Torque and Angle correction coefficients
Two coefficients to correct the torque and angle reading can be stored on the end-fitting tool. These
coefficients are used to correct the torque and angle measure when an extension is used on the STwrench.
The torque correction coefficient is used also to compensate the torque measurement when a torque
multiplier is used on the STwrench.
WARNING: Starting from firmware version 3.1, the Torque Correction Coefficient is given to
two decimal places. The end-fitting tools programmed with the STwrench using firmware 3.1x
or later cannot be used on STwrenches with firmware 3.0x or before (however, they will work if
re-programmed with firmware version 3.0x or before).
NOTE: These coefficients are not considered in the Free Mode.
Neither are they considered if the tool recognition function on the STwrench is disabled.
When using an extension, the black end-fitting tool should be welded to the extension in
order to maintain the automatic tool recognition and correction coefficients utilization.
If these two coefficients are already known, simply write them in this window and click on Set to store
them in the RFID TAG of the end-fitting tool plugged into the smartHEAD. The Angle coefficient is
referred to a Torque nominal, which must be specified together with the coefficient. The Torque Nominal
is the torque value at which the bending angle has been measured.
If these two coefficients are not already known, see the chapter Appendix A – Calculating Torque and
Angle Correction Coefficients for a detailed description on how to calculate them.
NOTE: It is also possible to define these coefficients in the Pset parameters (see the Pset
Options) instead of writing them in the end-fitting tool TAG. This can be used when you use an
extension without the black end-fitting tool.
