    9 Weighing mode The sequence of a simple weighing process is described in the chapter on Weighing below. Apart from the work steps described there (simple weighing, reset to zero, taring) the weighing balance offers additional options for adapting the “Weighing” application to your requirements.

  • Page 35: Weighing With Tare

    9.1.3 Weighing with tare  Taring The dead weight of any weighing container may be tared away by pressing a button, so that the following weighing procedures show the net weight of the goods to be weighed. • Place the weighing container on the weighing pan and close the draft shields, as required.

    17 Parts counting Before the balance can count parts, it must know the average part weight (i.e. reference). The balance determines the total weight and divides it by the number of parts (the so-called reference quantity). Based on the calculated reference, single weight counting will follow next.
