The "--OL--" message indicates that the weight on the pan has exceeded the balance's maximum rated capacity (e.g., 220g).
Immediate Action:
1. Immediately remove the item from the weighing pan to prevent damage to the high-precision load cell.
2. If "--OL--" remains visible while the pan is completely empty, it indicates a catastrophic load cell failure, likely caused by severe physical shock. Please contact an authorized Aczet service center.
