5.8.3 Adjusting with external weight (only KERN EW and EWB)

Carry out adjustment with the recommended adjusting weight (see Chapter 1 „Tech-
nical Data“). The adjustment can also be carried out with different adjusting weights
(see table), but not ideal from a metrological point of view. Information concerning
the adjusting weights is available at:
