Needle
The "indicating" needle displays torque as it is
applied. The "setting" needle is used to select
and pre-set torque.If the "setting" needle has
been used to pre-set torque, the operator must
apply torque until the "indicating" needle meets
the "setting needle." At this point pre-set
torque has been reached.
Please Note: If you use your torque wrench with any kind of extension, the torque applied will be greater
than that displayed on the dial. To calculate the increase, the formula indicated fig 4 should be used.
