TORQUE CALIBRATION SYSTEM SETUP CHAPTER 4
4-1
13. While holding the power tool drive perfectly in-line with the transducer drive, reinstall
the tool onto the simulator and energize the tool until its motor stalls or, if featured, the
tool clutch slips. Be careful not to add torque by turning the tool by hand.
14. Release the torque and note the Power tool reading on the display.
15. CLEAR the display.
16. Repeat steps 4 through 15 in the opposite direction, if required.
Given the variables typical of power tools and fastener joint dynamics, a number of
readings should be taken and averaged to best determine the accuracy and repeatability
for each tool.
