(If this appears correctly) it should be ÂµA but it's quicker to type uA. Answer: UA stands for Urine Analysis.. When you pee in a cup and the doctors take it and analyze it to see if you or whoever has done any drugs or drank any alcohol in the past two weeks. Microamperes. The u is the closest letter many computer keyboards have to the Greek mu symbol.
Do not blind other drivers with your high beam headlights. Dim your lights by switching to low beams before you are 500 feet from a vehicle coming toward you. If you are following another vehicle, change to low beams when you get closer than 300 feet. Use your high beams whenever possible as long as it is not illegal (i.e., in open country when other cars are not near or on dark city streets when no other traffic would be affected by your high beams).
Therefore, I developed a laser bore sight calculator that should get me much closer to zero at 100 yards. The objective here is to determine how far above the red laser dot I should adjust a scope for a 100 yard zero when bore sighting a rifle at 25 feet.There were two pieces of information I needed to know before performing these calculations.ecause the barrel is at an angle, as we move farther from the bore the closer together the two lines become. So, to properly set up my scope, I need to know how far above the red dot the scope must be adjusted for at 25 feet so the rifle can be zeroed at 100 yards (or at least close).
