Rice Lake FX-i WP Series, A&D Weighing - Manual (Page 20)

18
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- PCS 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.
While the stabilization indicator is on, pressing the PRINT key
will output the weight value, using the RS-232C serial interface.
Note
Peripheral equipment, that is sold separately , such as a
printer or a personal computer is required.
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 and
averaging the unit mass variable to minimize the weighing error,
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.
