Counting Mode (pcs)
The balance weighs the sample pieces and calculates the unit weight.
Using the sample unit weight, the balance counts the number of items in the sample.
As for the minimum unit weight acceptable, refer to the item “
Umin
” of “

List
”.
Selecting the Counting Mode

former display. When the sample weight is light and
the counting error could become large, the balance
will request you to use a larger number of samples.
Place the displayed number of samples on the pan
and press the PRINT key to calculate and store
the unit weight. Refer to “Sample quantity error” and
“Unit weight error” in “

Counting Mode Using the ACAI Function
ACAI
TM
(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. After storing the unit weight at step 6, add a few
more samples on the pan. Then, the ACAI indicator
turns on. (Add more than three pieces. The ACAI
indicator will not turn on for the number of samples
beyond the ACAI range.)
9. The ACAI indicator will flash and the balance re-calculates the unit weight. Do not touch
the balance or samples on the pan until the ACAI indicator turns off.
