Electroscale Model 401 Bench Scale is a digital industrial weighing system with a 10‑lb capacity and 0.001 lb resolution, typically used in laboratory or process control environments. Common failure modes for this class of bench scales include drift or loss of calibration due to sensor degradation, power supply instability causing erratic readings, and controller board faults such as blown fuses or corrupted firmware. Initial troubleshooting should verify that the unit receives clean 24 V DC from its power supply, inspect the load cell wiring for loose connections or corrosion, and check the display/CPU board for visible damage or error codes before proceeding to component replacement.[oss-gpt-20b]
