Question 1: Here's what my torque wrench looks like at rest:



You can see that it's not zeroed out. From my Intergoogling, it looks like I can calibrate/fix it by simply bending the pointer beam until it is at zero. Correct?

Question 2: Here's the torque info on a stem:



I think it says "TORQUE: 40 ln-lbf [4.5n-m]"

Am I correct that this means I should use my torque wrench, and apply pressure until the (newly calibrated) needle points to 40 FOOT-POUNDS?

Thanks!
