BM series 23
Counting mode using the ACAI function
The ACAI is a function that improves the accuracy of the unit mass automatically by increasing
the number of samples as the counting process.
ACAI: Automatic Counting Accuracy Improvement
Proceed to step 8 after storing a unit mass at last page.
8 If a few more samples are added, the processing
indicator turns on. To prevent an error, add three or
more. The processing indicator does not turn on if
overloaded. Try to add the same number of samples
as displayed.
9 The balance re-calculates the unit mass while the
processing indicator is blinking. Do not touch the
balance or samples on the pan until the processing
indicator turns off.
10 Counting accuracy is improved when the processing
indicator turns off.
Each time the above operation is performed, a more
accurate unit mass will be obtained. There is no
definite upper limit to the ACAI range for the number
of samples exceeding 100. Try to add the same
number of samples as displayed.
11 Remove all the samples used in ACAI and proceed
with the counting operation using the improved unit
mass.
From step 6
at last page
Add a few more
samples.
The mark turns on
at proper range.
The mark turns on
and off during
calculation.
The mark turns off
after the unit mass
is improved.
