Characterize scale output
| Continuous | Frames arrive repeatedly; select and timestamp stable readings. |
|---|---|
| Request/response | Send the documented command and correlate one response. |
| Status fields | Interpret stable/motion, overload, sign, tare, net/gross and units where provided. |
Capture raw known weights to establish framing, decimal placement, signs and unit codes. Do not infer decimal scale from one sample.
Implement defensively
- Verify serial settings and delimiters.
- Buffer partial frames and reject malformed status.
- Apply timeouts appropriate to settling and polling.
- Store raw frame with normalized value for diagnosis.
- Validate reconnect and device-zero/tare workflows.
