Torque Spec Question - basic

[Pablo M]

Now that I've been digging into the mechanics of my new-to-me '72 02tii I've been looking for torque specs and came across these below. I also have Haynes manual, but couldn't find a torque spec for the oil drain plug so went searching further. 

 

My question is what does the +x and @1 mean? For example, the control arm connection shows torque to be 51 +14 @1. Does that mean 51-65 ft/lbs? Or something different? And what does the @1 mean?

@1 means Note 1, the car needs to be on the ground with 150lbs in each seat, a full tank and 46 pounds of luggage in the trunk on the left side.  The 51+14 are min/max in foot lbs for the nuts in question.  Some torque guides (like the one for head bolts) have an initial torque in ft/lbs and then a torque angle in degrees.  You use your torque wrench to set the initial setting, then a torque angle gauge to complete the final torque setting.

...but my torque wrench only goes to zero.

How do the negative torques work?
