The "Ovr Flo" display code signifies that a weight greater than the absolute maximum rated threshold of the scale has been placed onto the weighing pan. (For instance, over 220 grams on an AX-220 model).
Root Causes:
- Excess physical material resting directly on the pan.
- Shock loading or someone manually pressing downward on the sensitive scale platform.
- Permanent mechanical deformation of the Single Block Sensor system.
Corrective Diagnostics & Countermeasures:
1. Immediately clear all materials, weights, and containers off the stainless steel platter.
2. Inspect around the edges of the pan to guarantee no physical components are jammed or pressing down on the support mechanism.
3. Power cycle the machine off for 10 seconds and turn it back on.
Sales & Upgrade Advisory:
If your balance continues to lock onto "Ovr Flo" while completely empty, the high-precision magnetic force core sensor has suffered terminal strain damage. Replacing delicate sensor blocks can often equal the cost of an entirely new device.
