11-2. Error codes
Overload error
Warning to indicate that an object beyond the balance
capacity has been placed on the pan. Remove the object
from the pan.
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 weight error
The sample weight is too light to set the unit weight in the
counting mode or 100% reference weight in the % mode.
Sample quantity notice
When sample weight is light and the counting error could
become large, the balance will request you to use larger
number of samples. Place the displayed number of
samples on the pan and press the PRINT key to store
