12. COUNTING MODE (PC)

This is the mode to determine the number of objects in a sample based on the standard sample unit mass. The unit mass is the mass of one piece of the sample. The smaller the variables in each sample unit mass are, the more accurate the counting will be. The AD-4212A/B series 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 (AD-4212A-100, AD-4212B series) or 10 mg or more (AD-4212A-200/600/1000) 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

1Set “Unit selection ( Unit )” parameter of the function table to pC (counting mode). For details, refer to “5-2 Changing the Unit”.

Storing a sample unit mass

2Press the SAMPLE key to enter the sample unit mass storing mode.

To return to the counting mode without storing the sample unit mass, press the CAL key.

3To select the number of samples, press the SAMPLE key several times. It may be set to 10, 25, 50 or 100.

Note

A greater number of samples will yield more accurate counting result.

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

e.g.: 25 0 pC 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. The balance displays 25 pC (counting mode) and is set to count samples with this unit mass. (The sample unit mass stored, even if the AC adapter is removed, is maintained in non-volatile memory.)

To improve the accuracy of the unit mass, proceed to step 8.
