17.2 Test Execution
Once the STwrench has been programmed by Torque Supervisor, the list of Psets to test the joints is
available in the Prog. Mode menu:
Execute the tests and then download the results from Torque Supervisor. Partial results are downloaded
from the STwrench memory anyway (in which case the statistics are generated only when the remaining
test results are executed and downloaded).
17.3 Tightening Strategies and Parameters
Torque Supervisor defines the Pset parameters and the test method. The following table provides a cross
reference between the parameters and test methods inside Torque Supervisor and the Pset parameters of
