9.3.3 <P2.2.1.3> Auto zero function
This function is used to automatically tare minor weight fluctuations (such as minor
soiling on weighing pan). By enabling this function you automatically ensure that
each weighing process starts with zero display.
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.
