5-2 Counting Mode (PCS)
This is the mode to determine the number of objects in a sample based on the standard sample unit
mass. Unit mass means the mass of one sample. The smaller the variables in each sample unit
mass are, the more accurate the counting will be. The FX-i series balance is equipped with the
Automatic Counting Accuracy Improvement (ACAI) function to improve the counting accuracy.
Note
If the sample unit mass variable is too large, it may cause a counting error.
Selecting the counting mode
1 Press the MODE key to select 1pcs (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 5, 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 come on. Press the
PRINT key to calculate and store the unit mass. The
balance displays 25
pcs
(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.
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.
