8.2 Dosage und Zero-tracking
When the Auto-Zero-function is activated, any slight changes of the zero readout are
automatically tared.
In the event that small quantities are removed or added to the material to be
weighed, incorrect weighing results can be displayed due to the “stability compensa-
tion“ in the balance. (Example: Slowly draining fluids from a container on the bal-
ance.)
Having dosages with slight changes of weight it is recommended to deactivate this
function.
With switched off Zero-Tracking the display however is more unstably.

8.3 Select the adjusting weight
The calibrating weight can be selected from four prescribed nominal values (1/4; 1/2;
3/4 or max.) on the KERN 440 model (also see Table 1, manufacturers settings grey
underlayed ). We recommend the selection of as high a nominal value as possible in
order to achieve high-grade measuring technique weighing results. Alternatively the
non-included adjustment weights can be purchased from KERN.
