What Data for This Category Looks Like
Data for this category primarily originates from metrology management systems in enterprise metrology rooms and quality laboratories, external calibration institution certificates, reference standards, LIMS systems, and environmental monitoring equipment. Daily maintained documents include measuring tool ledgers, calibration plans, calibration certificates, periodic verification records, original test records, reference material ledgers, and deviation handling documents. Data updates are triggered by calibration cycles, single test results, or abnormal events, with no unified fixed update cycle. Data fields include instrument number, calibration date, measurement uncertainty, traceability chain information, environmental parameters, and others. Some fields must conform to the standard format of the CNAS system.
Constraints Imposed by These Characteristics on HTTP Interfaces and External Systems
Data sources for this category are scattered, and updates have no fixed cycle. HTTP interfaces must support event-triggered calls to adapt to real-time scenarios such as calibration completion and abnormal deviations. Data includes core compliance fields such as traceability chain and measurement uncertainty. Interfaces must strictly return specified fields to support quality judgment, and must not omit key information. Data confidentiality requirements are high. Interfaces must include permission verification mechanisms to prevent leakage of sensitive metrology information. Data updates may affect past product traceability. Interfaces must support historical data queries to meet the need for tracing the impact scope of inaccurate instruments.
How to Configure
The following configurations apply to FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Carry a dedicated Bearer token | Ensure access to metrology data from external systems is permission-controlled, meeting confidentiality requirements for metrology information |
variables | Bind variables for instrument number and calibration cycle threshold | Adapt to personalized process specification and technical standard matching logic for different measuring instruments |
responseData | Include traceability chain and measurement uncertainty fields | Match the standard structure of documents in this category, supporting quality judgment and compliance review |
| Single search upper limit | Top 3 entries | Avoid excessive non-critical data interfering with precise matching of process specifications |
| Maximum context | 800–1200 characters | Adapt to the conventional length of single documents such as calibration certificates and original test records |
| Timeout period | 60 seconds | Meet the conventional response timeliness requirements for metrology data interfaces |
Three Common Misconfigurations
- Symptom: After calling the configured HTTP interface, an empty result is returned, and the corresponding process specification is not matched. Cause: The
variablesparameter was not correctly configured to bind the measuring instrument number, making it impossible to locate the corresponding process specification and technical standard documents. - Symptom: After importing a metrology ledger CSV file uploaded via the API, question and answer pairs cannot be correctly generated. Cause: The import mapping was not configured according to the field rules of documents in this category, causing the question and answer matching logic to fail.
- Symptom: The result returned by the interface request does not include traceability chain data. Cause: The required metrology-specific fields were not specified in
responseData, preventing external systems from obtaining key evidence required for compliance review.
How to Verify Correct Configuration
- Initiate a simulated request carrying the specified
variablesparameter, and check whetherresponseDataincludes the traceability chain and measurement uncertainty fields. - Upload a standard CSV file that conforms to metrology document formats, and verify that the field correspondence for question and answer matching is correct after import.
- Simulate a request without a valid
Authorizationtoken, and confirm that the interface returns a permission error status code as expected. - Configure a trigger test based on the calibration cycle, and verify that question and answer responses are normal across different update scenarios.
