Make sure to use weights that have the accuracy of Class 2 standard weight or highter, and carry out

the following procedure for span adjustment.

Get the weights for 500 increments, 1/2 weighing capacity and full weighing capacity to perform span

adjustment. For example, to calibrate the scale with weighing capacity of 30kg, 2 sets of weights total-

ing 15kg and a 5000g weight are necessary.

Caution: Span adjustment may not be made properly in a place exposed to vibrations or wind therefore

avoid such places.
