8.3.2 Dosing and Zero-tracking
The Auto-Zero function is used to tare small variations in weight
automatically.
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 compensation". (Example: Slowly
draining fluids from a container on the balance).
When apportioning involves small variations of weight, it is
advisable to switch off this function.
If Zero-Tracking however is switched off, the weighing display
becomes more busy.
