9-10. 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 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 balance is equipped with the
Automatic Counting Accuracy Improvement (ACAI) function to improve the counting accuracy.
Notes
For counting, use samples with a unit mass of at least ten or more times the minimum
weighing value of the balance.
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
1 Press the MODE key to select (counting mode).
Storing A Sample Unit Mass
2 Press the SAMPLE key to enter the sample unit mass storing
mode.
Even in the storing mode, pressing the
MODE key will switch
to the next mode.
3 To 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 is displayed if 25 is selected in step 3.
5 Place the number of samples specified on the pan.
In this example, 25 pieces.
6 Wait for the stabilization indicator to turn on. Press the
PRINT key to calculate and store the unit mass. The
balance displays (counting mode) and is set to
count samples with this unit mass. To improve the
accuracy of the unit mass, go to step 8.
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 0.0001 g is used and 10 pieces
of samples weigh 0.0005 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. For example, 1
50-
appears to require 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.
