Tablet puzzle- Logical/Mathematical

There are 10 machines which produces tablets. If everything is fine the tablet weighs exactly 10 grams each. There is one machine which is faulty and produces tablet which weights 9 grams instead of 10. The riddle is to find out which is the faulty machine given a condition that you can only weigh only once using a digital weighing machine.
The produced tablet from 10 machines is constantly draining in a sack numbered 1 to 10 where 1 corresponds to machine 1 and so on so forth. You can pick up tablets from any of the sacks and how much ever you want but can weigh only once. That is the digital weighing machine will shows the reading only once and you should be able to point out which machine is at fault.
