Marine Chronometer Gimbal Purpose Lookup
Return the bowl, ring-gimbal, box, handling, or lock-state function of a historical marine chronometer and its carrying case.
Description
Gimbals use pivoted supports to help a marine chronometer retain orientation aboard a moving ship.
Gimbals use pivoted supports to help a marine chronometer retain orientation aboard a moving ship. The bowl and box also provide enclosure and handling functions.1
Return the bowl, ring-gimbal, box, handling, or lock-state function of a historical marine chronometer and its carrying case.
When to use Marine Chronometer Gimbal Purpose Lookup
Use this tool to return the bowl, ring-gimbal, box, handling, or lock-state function of a historical marine chronometer and its carrying case.
Choose a supported reference focus or prepare the watch measurements, evidence and explicit limits requested. Confirm units and date conventions before running.
How to use Marine Chronometer Gimbal Purpose Lookup and understand its results
- Choose a supported reference focus or prepare the watch measurements, evidence and explicit limits requested. Confirm units and date conventions before running.
- Enter gimbalFocus using the field table and calculation rules, then run the tool.
- Read gimbalFocus, keyDate, verifiedStatement. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| gimbalFocus | Marine chronometer gimbal focus | string; one of "bowl", "gimbal", "box", "handling", "lockCaution" | Required |
Select an exact supported gimbalFocus value from the field table and run the lookup. The implementation selects a fixed local table entry and returns the fields shown below. Matching is case-sensitive, with no trimming, synonyms or free-text search. Any keyDate output can be a date, period or context label.
result=stored entry for selected focus Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| gimbalFocus | Marine chronometer gimbal focus | string |
| keyDate | Marine-use context | string |
| verifiedStatement | Verified gimbal statement | string |
{
"input": {
"gimbalFocus": "gimbal"
},
"output": {
"gimbalFocus": "gimbal",
"keyDate": "marine use",
"verifiedStatement": "Two pivoted rings called gimbals supported the bowl so the chronometer could remain closer to level as the ship rocked."
}
}Limitations and assumptions
No shock protection, operating state or instrument condition is verified. No sources are fetched or statements updated at runtime.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
