) = For operation with greater preload setting, please send e-mail to request PC configuration software; e-mail address: fast.factory@sartorius.com
Greater preloads are possible, but reduce the weighing capacity.

) = The weighing time is the time period in which the measured value oscillates within a range of ±3x the standard range of the static end value.
Test weight approx. 25% of max.
