NNoottee -- A weight of known amount is required to calibrate the scale system. Use a 100 lb (45 kg) or two 50 lb (22.6 kg)
weights to complete this procedure. The weight(s) must be ± 0.5 lb (0.2 kg) at 50 lb (22 kg) or less or ± 1.0 lb (0.4 kg) at ≥
50 lb (22 kg) when flat to ensure scale system precision. If the weight(s) do not have the required tolerance, a controlled
weighing must be made to determine their weight is within the ± 0.5 lb (0.2 kg) at 50 lb (22 kg) or less or ± 1.0 lb (0.4 kg) at
≥ 50 lb (22 kg) when flat tolerance.
