How do you calibrate a rangefinder lens?

How do I know if my car has a rangefinder alignment?

A quick test is to take a ruler/yard stick, and use it to measure out the distance from the film plane to an object. Use the rangefinder to align the double image of the object, and read the lens barrel focus distance. It should be the same as the measured distance..
