You don't need to send it anywhere - use physics instead 
Torque = Force * Distance
How long is the torque wrench? Let's call it distance d.
Get a brick, of weight w.
For "d = 1 ft" and "w = 1 lb", you could apply 1 ft-lb of torque.
Set the torque wrench to 1 ft-lb.
Attach the torque wrench to a securely fastened bolt somewhere.
Balance brick on torque wrench (or, use a scale to apply your known force to the end of the torque wrench).
You are now applying a known torque to your torque wrench. See if it clicks Vary the forces around your target so make sure that it doesn't click for just under 1 ft-lb. Make sure it clicks for just over 1 ft-lb. I'm sure there are plenty of variations on this method that would probably be more interesting and accurate, but that's what I could come up with at 7:55am.
