Overload error
Warning to indicate that an object beyond the balance
capacity has been placed on the pan. Remove the object
from the pan.
Warning to indicate that the balance detects an
unexpected load. Remove all objects from the pan or
check that the weighing pan is correctly installed.
Range over notice
This will be shown if the weight sensor receives strong
force upward. Check if there is anything sandwiched
around the weighing pan. There is a possibility that the
weight sensor itself may have a failure.
Unit / 100% weight error
The unit / 100% weight is too light in the counting / %

Sample quantity notice
When sample weight is light and the counting error could
become large, the balance will prompt you to use a
larger number of samples. Place the displayed number of
samples on the pan and press the PRINT key to store
the unit weight.
Note: Pressing the PRINT key without adding
samples may reduce counting accuracy.
Starting from the 100 samples, 100 - may
be displayed when the sample weight is light.
This is for your notice and press the PRINT
key without adding any samples.
When “aCai 0” (ACAI disabled) or “Umin 2” is
set, this notice is not shown.
