ABSTRACT:
A scale having a base provided with spaced first and second upright posts, a beam having an intermediate portion pivotally mounted by the first post, a pan dependingly pivotally mounted by the beam first end portion remote from the posts, the beam having a first series of serrations between the first post and the pan and first graduated indicia in registry with the first serrations, a second series of serrations and second indicia in registry with the second serrations on the opposite side of the first post from the first serrations, a third series of serrations and third indicia on the opposite side of the second serrations from the first post, and comparator scale indicia on the beam second end portion that are in the same plane as the resting point locator indicium on the second post and closely adjacent thereto and a poise for each series of indicia. Each of the second series of graduations is equal to one unit of weight, each of the first series equal to 0.1 unit of weight and each of the third series equal to a 0.01 unit of weight. As a result, the final and fine adjustment is with the poise on the beam very close to the stationary resting point locator indicia. This makes it easier to make the final adjustment as the user does not have to shift his eyes from left to right consistently while making the final changes of the third poise.
