The tolerance is the maximum number of scale divisions allowed for a scale to be acceptable for official test weighing without further adjustment. Scale definition is - an instrument or machine for weighing. Most analytical balances also have a tolerance for off center balance: Here you would take a test weight, measure it at the center of the pan, and then measure the same weight at the edge of the pan in all four quadrants. Consequently, to offset the possibility of interference between mating threads, the minor diameters of the UNJ internal threads had to be increased. A Beam balance (or Beam scale) is a device to measure weight or mass. increments when using a 10 lb.
