    6 Weighng Mode You can select a Weighng Mode from four types in Function 1: weighing machine, parts counting, percentage weighing, and unit converting. All the Weighng Mode support additional functions (or the accumulation function and the limit function) depending on the unit to use. Measurement Modes When you select a Weighng Mode and additional functions, you can weigh samples in different ways as shown below.

  • Page 23: Parts Counting

    Parts Counting The parts counting function employs an automatic memory update method, also referred to as a Self Counting System. When you put a specified number of samples on the balance, and put additional samples, the balance automatically updates the average unit weight of the samples. However, you cannot add more than three times as many samples as the first reading.
