Notes

If the balance judges that the mass of the samples is too light and is not adequate to be used as the unit mass, it displays lo . In that case, store the mass by some quantity. For example, when the model with the minimum weighing value of 0.01 g is used and 10 pieces of samples weigh 0.05 g. Store 100 pieces of samples as 10 and multiply the weighing result by 10.

If the balance judges that the mass of the samples is too light to aquire accurate weighing, it displays an error requiring the addition of more samples to the specified number. In the example above, 50- pC appears, requiring 25 more samples. Add 25 samples and press the PRINT key. When the unit mass is stored correctly, the balance proceeds to the counting mode.

Counting operation

7Place the samples to be counted on the pan.

While the stabilization indicator is on, pressing the PRINT key will output the weight value, using the RS-232C serial interface.

Note

Peripheral equipment, that is sold separately, such as a printer or a personal computer is required.

Counting mode using the ACAI function

The ACAI is a function that improves the accuracy of the unit mass automatically by increasing the number of samples and averaging the unit mass variable to minimize the weighing error, as the counting process proceeds.

Place sample to be counted

The counting result

8If a few more samples are added, the processing indicator turns on. To prevent an error, add three or more. The processing indicator does not turn on if overloaded. Try to add the same number of samples as displayed.

9The balance re-calculates the unit mass while the processing indicator is blinking. Do not touch the balance or samples on the pan until the processing indicator turns off.

10Counting accuracy is improved when the processing indicator turns off.

Each time the above operation is performed, a more accurate unit mass will be obtained. There is no definite upper limit of ACAI range for the number of samples exceeding 100. Try to add the same number of samples as displayed.

11Remove all the samples used in ACAI and proceed with the counting operation using the improved unit mass.
