CONVERSION FORMULA
Correct dial or scale readings are determined by the use of the following formula:
Correct
=
Required
Length of torque wrench + Length of adapter
Reading
torque value
Length of torque wrench
NOTE
The length of the torque wrench is measured from the center of the
handle to the center of the drive. The length of the adapter is
measured from the center of the drive to the center of the wrench.
In this example, the torque wrench measures 22 in. (55.9 cm) and the adapter is 3 in. (7.6 cm). The required
torque is 19 lb-ft (25.8 Nm).
19 lb-ft (25.8 Nm)
Correct Reading
=
22 in. (55.9 cm) +3 in.
