WHEN CHANGING THE TYPE OF HEAD
◼ If you use the different head of the wrench, the
reading on the display will be different for the
different length of the head. Please refer to the
following explanation.
D = D1 * (L3+L1) / (L3+L2)
D : The set torque
D1: The actual torque applied to the nut.
L1: The normal length
L2: The extended length
L3: The length from the fitting pin to the
calibration point.
