11.4 Auto Zero
Under this menu item the automatic zero point correction can be switched on or off.
In switched-on-state the zero point is automatically corrected at drift or when dirty.
Note:
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“. (e.g. slow flow of liquids from a container placed on the balance,
evaporating processes).
When apportioning involves small variations of weight, it is advisable to switch off
this function.
