Description
Label a device's supplied calibration-timestamp transcription and source.
Eye records preserve laterality, reference axes, chart distance, calibration provenance and geometric scale. Disc-diameter units are a relative image scale, not a physical length, and cylinder sign differs from a full prescription transformation. Supplied labels and conversions do not inspect an eye, detect disease or choose care.
Label a device's supplied calibration-timestamp transcription and source.
When to use this tool
Use Ophthalmic Device Calibration Timestamp when you already have deviceId, recordedTimestamp, source and need to label a device's supplied calibration-timestamp transcription and source.
How to use the tool and how it works
- Enter deviceId, recordedTimestamp, source. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read label. Use the output convention below.
Require deviceId/recordedTimestamp/source nonempty; JSON-quote the timestamp in the label.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| deviceId | Device Id | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| recordedTimestamp | Recorded Timestamp | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| source | Source | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| label | Label | Required. Text; maximum UTF-16 length 8192. |
{
"input": {
"deviceId": "D17",
"recordedTimestamp": "2026-11-01T10:30:00Z",
"source": "Service record"
},
"output": {
"label": "D17; calibration=\"2026-11-01T10:30:00Z\" [Service record]"
}
}Limitations and assumptions
- The timestamp is not parsed and no calibration validity, service need or device performance is verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Review the original image calibration, refraction convention and chart-distance record for substantive measurements. Use complete optical or image geometry when physical scale or clinical interpretation is required; relative disc units and axis labels preserve narrower conventions.
