2. Calculate the deviation in torque measurement between the TBP tool and STa6000:
Torque measurement factor deviation = 100x [TBPmean-STa6000 mean]÷STa6000 mean
Result for pass is ± 2.0%
3. Normalize the result from the TBP to achieve the same mean value as for the STa6000:
TBP normalized (1…30) = TBP value (1…30) x STa6000 mean÷TBP mean
4. Calculate the deviation between the STa6000 and the POWER FOCUS 6000 for each tightening:
Deviation (1...30) = TBP normalized (1...30) - STa6000 value (1...30)
5. Calculate the standard deviation (Sigma) for the 30 deviations calculated:
6. Check of torque measurement accuracy in relation to the tool maximum torque (ToolMax), specified per
tool model, e.g. 55 Nm for TBP8.
Torque measurement accuracy = 100 x 3 x StdDev)÷ToolMax
Result for pass is: maximum 4.0%
