If the balance judges that the sample weight is

too light to acquire accurate weighing data, it
displays an error prompting the addition of more
samples to the specified number.
Add the specified number of samples and press
the ENTER key.
Refer to "12-2. Error Codes."
If the balance judges that the sample unit weight

is too light and cannot be stored as the unit
weight, it displays
previous display.
Even in this situation, the unit weight may be
stored using the function setting "Umin 1" or
"Umin 2." However, the counting results are for
reference only.
Counting the objects
7. Place the objects to be counted on the pan.
The balance counts the objects using the stored
unit weight and displays the counting result.
Counting mode using the ACAI function
TM
ACAI (Automatic Counting Accuracy Improvement) is a function that improves the
accuracy of the unit weight by increasing the number of samples as the counting
process proceeds.
8. If a few more samples are added to the sample
in step 6 after the unit weight is stored, the ACAI
indicator turns on.
Add the same number of samples as displayed.
(The ACAI indicator will not turn on if
overloaded.)
9. The balance re-calculates the unit weight while the ACAI indicator is blinking. Do not
touch the balance or samples on the pan until the ACAI indicator turns off.
10. Counting accuracy is improved when the ACAI indicator turns off. Each time the
above operation is performed, a more accurate unit weight 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.
