6.3.Counting Mode (PCS)

This is the mode to determine the number of objects in a sample based on the standard sample unit mass. The unit mass means an average mass of the samples. The smaller the variation in the samples, the more accurate the count will be. The balance is equipped with the Automatic Counting Accuracy Improvement (ACAI) function to improve the counting accuracy.

Notes

Use samples with a unit mass of 1 mg or more for counting.

If the sample unit mass variable is too large, it may cause a counting error.

To improve the counting performance, use the ACAI function frequently or divide the samples into several groups and count each group.

Selecting the counting mode

key to enter the sample unit mass storing mode.

3 To select the number of samples using the	RANGE	key.
It may be set to 10, 25, 50 or 100.
Advise A greater number of samples will yield		more
accurate counting result.

4 Place a container on the weighing pan, if nec essary. Press the RE-ZEROkey to cancel the weight (tare). The number specified in step 3 appears.

Example: 25 0 pcs is displayed if 25 is selected in step 3.

5Place the number of samples specified on the pan. In this example, 25 pieces.

6Wait for the stabilization indicator to be displayed.

Press the PRINT key to calculate and store the unit mass. Then the balance displays 25 pcs and is set to count samples with this unit mass. (The sample unit mass is stored in non-volatile memory, and is maintained even if the AC adapter is removed.) To improve the

accuracy of the unit mass, proceed to step 8.

Notes

If the balance judges that the mass of the samples is too light (under 0.0001g) and can not be stored as the unit mass, it displays lo .

If the balance judges that the mass of the samples is too light to acquire accurate weighing, it displays an error requiring the addition of more samples to the specified number.

Example: 50 - pcs appears, requiring 25 more samples. Add 25 samples and press the PRINT key. When the unit mass is stored correctly, the balance proceedes to the counting mode.
