How to Calibrate a Torque Wrench
Calibration temperature
Calibration shall be performed at the ambient temperature in the 18 to 28°C range.
Temperature variations shall be within ±1°C.
Check the following points before starting calibration of a torque wrench
(1) Place the torque wrench tester on a stable workbench.
(2) For direct-reading type torque wrenches, read the measurement value in a direction perpendicular to the scale or dial (Parallax correction).
(3) For click-type torque wrenches (QL/SP, etc) do a warm-up operation by loading the maximum torque of each model for both directions 5 times before testing.
(4) For direct-reading type torque wrenches (CEM/DB/F type, etc), do a warm-up operation by loading the maximum torque of each model for both directions once, and make sure the pointer, or the digital display shows "0" after loading.
(5) Apply load at the center of the grip or at the marked loading point within the specified range
Precautions in Calibration
(1) For click-type torque wrenches (QL/SP, etc), load the initial torque up to 80% of the target torque, then apply the rest slowly and evenly. (take 1 - 3 seconds to apply the last 20%.) Pre-set type torque wrench (except single-purpose type such as QSP) must start at low level, then adjust to the target torque. (Do not adjust to the target torque by lowering from the higher level.)
(2) For direct-reading type torque wrenches (CEM/DB/F, etc), apply torque up to the target torque with attention not to exceed the target torque. If you exceed the target torque by mistake, please release torque down to zero and do the process from scratch.
