Question : How do you get even numbers like 5 or 10 nm?
Answer : To get even numbers like 5 or 10 nm, there are marks on the dial that sits on top of the black handle that increase from 0 to 9 in-lb and from 0 to 1.02 nm.
Question : Will this Tekton TRQ21101 1/4-inch work to torque car valve cover gasket screws to 7 lb/ft?
Answer : Yes, it should work. 7 ft. lbs. converts to 84 in. lbs. The range of this wrench works between 10 in. lbs. and 150 in. lbs.
Question : Do I need to calibrate this torque wrench before using or does it come pre-calibrated?
Answer : It comes calibrated to +/- 4% accuracy, so you do not need to calibrate it yourself.
Question : Is the 4% calibration averaged over the full range or is it 4% accurate no matter which setting?
Answer : It has an error of plus or minus 4% averaged over the full range, which means that the maximum error could and should be 4% over or under the setting value.
Question : Are the numbers etched and painted or just painted on the Tekton TRQ21101 1/4-inch torque wrench?
Answer : The numbers are not etched. They are painted.
