How would I calibrate a Dial Torque Wrench?

How would I calibrate a Dial Torque Wrench? This is the Dial type with the round, glass enclosed face with a needle indicator. The indicator is on approx. 76 ft lbs, quite a ways off from zero. I'm hoping there is a way for me to calibrate it myself. I searched the net but couldn't find an answer. Any help would be greatly appreciated!!
