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 proceeds.
ACAI: Automatic Counting Accuracy Improvement
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. 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.
Note ACAI will not function on the unit mass entered using the keys, or digital input
mode.
Add a few
more samples.
The mark turns on and
off during calculation.
The mark turns off after
the unit mass is improved.
From step 7
Repeat
The mark turns on
at proper range.
