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 on the previous 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.
Add a few more
samples.
The indicator turns
on at proper range.
The indicator blinks
during calculation.
The indicator turns
off after the unit
mass is improved.
