Notes
If the balance judges that the mass of the samples is too
light and is not adequate to be used as the unit mass, it
displays lo .
If the balance judges that the mass of the samples is too
light to aquire accurate weighing, it displays an error
requiring the addition of more samples to the specified
number. In the example above,
1 50-
pC
appears,
requiring 25 more samples. Add 25 samples and press
the PRINT key. When the unit mass is stored correctly,
the balance proceeds to the counting mode.
Counting operation
7 Place the samples to be counted on the pan.
Note
Up to 20 unit masses can be stored in memory for the
multiple sample. For details, refer to “12. DATA MEMORY”.
The unit mass data in memory can be recalled or changed
using commands from the computer.
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.
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 of 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.
