External Linearization with User-Defined Weights
Setup Information
– This function is accessible only if the software and the functionality of the
connected weighing platform permit this operation.
– External linearization when weighing in legal metrology is only possible when
the menu access switch is open.
– The
J
key must be assigned the “External linearization“ function,
see “Function Allocation of the
J
Key for Linearization and Setting/Deleting
the Preload.“
– Activating the display of geographical data has no effect on this function.

Once linearization has been completed, the
J
key must be reallocated back
to its original function in the Setup menu, e.g. external calibration/adjustment with
