The digi sm500 scale user manual lists several error codes. Here’s what they mean and how to resolve them:
| Error Code | Meaning | Solution |
|------------|---------|----------|
| EEEEE or O-LD | Overload – weight exceeds capacity | Remove weight immediately. Check load cell for damage. |
| Err Z | Zero range error (<-2% or >+2% of capacity) | Remove debris from platform. Press ZERO. Recalibrate if needed. |
| Err C | Calibration error | Repeat calibration with correct weight. Ensure no movement. |
| Lo Bat | Low battery (if battery option installed) | Replace batteries or connect AC adapter. |
| Err 1 | Load cell signal too low | Check load cell cable connection. Load cell may be damaged. |
| UnSt | Unstable environment | Stop air flow, use stable table, wait for vibration to cease. |
| Error | Meaning | Solution |
|-------|---------|----------|
| EEEEE / O-Ld | Overload (>500 g + 5%) | Remove weight immediately |
| U-Ld | Underload / pan missing | Install pan, check for obstruction |
| Err-C | Calibration error | Repeat calibration with correct weight |
| Err-2 / Lo | Low battery | Recharge (if battery model) or use AC |
| Stable not appearing | Vibration/draft | Move balance, close windows |
| Drifting numbers | Warm-up incomplete or air currents | Wait 30 min, use draft shield |
| CAL Err | Weight too light/heavy | Use exact specified weight | digi sm500 scale user manual
You need a 500g or 200g calibration weight (F1 or M1 class).
If
CAL Errappears: check weight is correct, pan is stable, no drafts. The digi sm500 scale user manual lists several error codes
Press UNIT (or MODE) repeatedly to cycle through:
Note: Precision may slightly vary by unit due to rounding. If CAL Err appears: check weight is correct,
The SM-500 usually supports multiple label formats. In Program Mode, navigate to the Format Setup menu to select a label size that matches your sticker roll (e.g., 40x30mm or 50x40mm).
