cERTIFIcATION
This torque wrench as calibrated at the factory, is
certified to meet the current ASME specification.
Additionally, all wrenches are calibrated on a torque
standard traceable to the National Institute of
Standards and Technology (N.I.S.T.).

USE OF ExTENSIONS
ANd AdAPTERS
When using an extension or adapter (increasing the
effective length of the torque wrench) the output
torque value will change. To calculate the new torque
output of the wrench use the following formula:
TW =
TA = Torque exerted @ end of adapter
L = Distance between square drive and hand position
TW = Wrench scale reading
A = Length of adapter or extension
TA
A
A number of variables can affect torque accuracy.
These include the length of an adapter or extension,
length of the wrench and variations in hand position
on the wrench will affect the accuracy of the above
calculation.
