Just drop the tension bar slowly with your hand underneath, but eventually your hand has to leave the dropweight. Otherwise you're pushing up in the opposite direction of the gravity, therefore reducing the tension you impart on the string.

For each pound you push down, you over-tension by about 15 pounds. Likewise, for each pound you push up, you under-tension by about 15 pounds.
