DETERMINING A WEIGHING AND REPETITION ACCURACY OF A PRECISION BALANCE

The invention relates to a method and a system for determining a weighing and repetition accuracy of a precision balance (1), in particular in a tablet testing system, which has a balance pan (3) on which a measurement object is placed. A positioning device (7) for positioning a reference weight (11) on the balance pan (3) in an automated manner, a drive unit for movably driving the positioning device (7) relative to the balance pan (3) and a determining unit are provided. While the balance pan (3) is empty, a taring measurement value for taring the precision balance is detected. A reference weight (11) is then positioned on the balance pan (3) in an automated manner by means of the positioning device (7) and a first weighing measurement value for the reference weight (11) is detected by means of the determining unit. The reference weight (11) is removed from the balance pan (3) and positioned on the balance pan (3) once again in an automated manner. A second weighing measurement value for the reference weight (11) is detected by means of the determining unit. The weighing and repetition accuracy of the precision balance (1) is determined from the detected weighing measurement values by the determining unit.
