I have tested my recently purchased weights kit with a calibrated analytical scale (1 mg accuracy): 50g weight: 50.015, 50.014 (<=0.03%) 1st 20g weight: 20.003, 20.004 (<=0.02%) 2nd 20g weight: 20.005, 20.005 (<=0.025%) 10g weight: 10.002, 10.003 (<=0.03%) 5g weight: 5.001, 5.001 (<=0.02%) 2g weight: 1.999, 2.001 (<=0.05%) 1g weight: 0.999, 1.000 (<=0.2%) 500mg weight: 0.500 (<=0.2%) 200mg weight: 0.200 (<=0.5%) 100mg weight: 0.099 (<=2%) 50mg weight: 0.050 (<=2%) 1st 20mg weight: 0.019 (<=10%) 2nd 20mg weight: 0.019 (<=10%) 10mg weight: 0.010 (<=10%) 1mg weight: 0.000 In cocnlusion, this calibration weight set provides a reasonable calibration solution for my small factory.
