When a unit mass is too light to store,
lo
appears in the display for a moment
and returns to the former display. When the
sample mass is light and the counting error
could become large, the scale prompts you
to use a larger number of samples. Place the
displayed number of samples on the pan
and press the MODE key to calculate and
store the unit mass.

Error codes.”
Counting the objects
7. Place the objects to be counted on the pan.
Counting mode using the ACAI function
ACAI
TM
(Automatic Counting Accuracy
Improvement) is a function that improves the
accuracy of the unit mass by increasing the
number of samples as the counting process
proceeds.
8. After setting the unit mass in Step 6, add a few
more samples on the pan. Then, the ACAI
indicator turns on.
Try to add the same number of samples as
displayed. The ACAI indicator does not turn on if
overloaded.
9. The ACAI indicator blinks and the scale re-
calculates the unit mass. Do not touch the scale
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 mass 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.
