Specifications¶
The specification management is used for defining and maintaining calibration requirements for inventories and types. Specifications determine which test conditions, intervals, and confidence levels apply to a calibration.
Overview¶
Specifications can be defined at two levels:
- Type Specifications -- Apply to all inventories of a specific type.
- Inventory Specifications -- Apply individually to a single inventory and override type-based defaults.
Columns¶
| Column | Description |
|---|---|
| Name | Designation of the specification (e.g., measurement range or test point). |
| Interval Value | Numeric value of the test interval. |
| Interval Unit | Time unit of the interval (D = Days, M = Months, Y = Years). |
| Confidence Level | Statistical confidence level of the specification (e.g., 95 %). |
| Type | Associated type designation, if the specification is type-bound. |
| Actions | Action menu for editing, duplicating, or deleting. |
Specification Details¶
Each specification can contain multiple detail rows that describe individual measurement points or test conditions.
| Column | Description |
|---|---|
| Description | Textual description of the measurement point. |
| Mode | Measurement mode or measurement function. |
| Range | Numeric measurement range of the specification. |
| Prefix | SI prefix (e.g., m, k, M). |
| Unit | Unit of measurement (e.g., V, A, Ohm). |
| Range Start / End | Start and end values of the valid measurement range. |
| Mode Start / End | Lower and upper limits of the measurement mode. |
| Tolerance | Permissible deviation (max. 500 characters, e.g., formula specification). |
| Resolution | Numeric resolution of the measurement point. |
| Sort Order | Order within the specification. |
Typical Workflows¶
- Create Type Specification: Define specifications at the type level so that all devices of the same type automatically receive the same test requirements.
- Import: Specifications can be imported from files to efficiently adopt existing requirements.
- Templates: Specification templates enable reuse and versioning of test requirements.
Technical Notes¶
Inheritance
Type-based specifications are automatically applied to all associated inventories. Individual inventory specifications take precedence.
- Specifications form the basis for the Test Steps and Measurement Results of a calibration.
- Changes to type specifications affect all future calibrations of the affected devices.
- Access requires the
