Disp Resolution Err
Disp Resolution Err - Invalid Capacity Configuration
⚙️ Model Compatibility: Essae DC-810 & DC-815 Label Scales.
The "Disp Resolution Err" message is triggered during the Power-On sequence if the scale's internal capacity and accuracy settings have been programmed incorrectly. Specifically, it occurs if the calculated ratio of (Capacity ÷ Accuracy) exceeds 15,000 divisions.
How to Fix This:
1. This is a configuration error, not a hardware failure.
2. You must enter the Settings Menu and correct the Basic Capacity and Accuracy parameters. (For example, a 15kg scale with a 1g accuracy equals 15,000 divisions, which is valid. Setting it to 0.5g would exceed the limit and cause this error).

Weight Overflow
Weight Overflow - Capacity Exceeded on DC-810
⚙️ Model Compatibility: Essae DC-810 and DC-815 Counting Scales.
The "Weight Overflow" (or simply "Overflow" in check weighing mode) message indicates that the load placed on the platter exceeds the machine's maximum rated capacity plus 9 divisions (Capacity + 9d).
Immediate Troubleshooting Steps:
1. Immediately remove the heavy load from the platter to prevent permanent strain on the aluminum load cell.
2. Power cycle the scale using the ON/OFF rocker switch.
Hardware Diagnostics:
If the scale displays "Weight Overflow" continuously when the platter is completely empty, the internal load cell or the Analog-to-Digital (ADC) conversion circuitry has sustained permanent mechanical shock damage.
Sales & Upgrade Note:
Industrial environments are tough on precision counting scales. If your load cell is permanently damaged, repairing a heavily used DC-810 might result in recurring downtime.
