This is similar to LensAlign. You want to use the following:
a tripod
shutter release or use timer (not the 2 second one either)
Distance = 25-50 x the lens focal length
Use a low ISO (400-800)(don't know which camera your doing)
Defocus and allow camera to acquire focus
Take one shot at "0" and look to see if it's back or front focusing (personally, I do this on the computer and not the camera screen), adjust accordingly, take another shot and repeat.
Av or M
Wide open aperture
Single point one shot

Which camera and lens are you calibrating?
Good luck.
