7 Weighing and Measurement Modes You can select from one of five weighing modes: weighing machine, parts counting, percentage weighing, unit converting, and gravimeter. In addition, the balance is equipped with addition and limit functions as additional functions. All the weighing modes except gravimeter support the additional functions (the addition function and the limit function) depending on the display unit.
8 Parts Counting When a specified number of samples are put on the balance, the balance divides the total weight of the samples by the number of samples to obtain the average sample weight. The balance stores the average sample weight based on the number of samples initially set. Additional samples, up to three times the initial number, can be added and the balance will automatically update the average sample weight.
Page 26
Finish sampling. Press the Function key to finish updating the memory. The average sample weight is saved and the balance returns to measurement mode. Counting the number of samples. After the average sample weight has been saved, the number of samples put on the balance will be displayed.
9 Percentage Weighing The weight of a reference sample is saved as 100%. When a sample is placed on the balance, the balance indicates the percentage of that sample with respect to the reference sample weight. A reference sample weight can be set by weighing an actual sample or entering a value. * Select [1.
