Quality Provisions

Quality Provisions define measurement range-specific requirements and tolerances that apply to calibration procedures. They are managed in the admin area and can be assigned to procedures.

Overview

Navigate to Administration --> Quality Provisions. The overview shows all stored quality provisions with their associated details.

Columns

Column	Description
Name	Unique designation of the quality provision.
Description	Explanatory text for the quality provision.
Created At	Date of creation.
Modified At	Date of the last modification.
Actions	Action menu for editing or deleting.

Create New Quality Provision

The New Quality Provision button opens the input form.

Field	Description	Required
Name	Unique designation (e.g., "DMM DC Voltage").	Yes
Description	Explanatory description of the provision.	No

The name must be unique system-wide.

Detail Lines

Each quality provision can contain multiple detail lines that describe individual measurement ranges and their requirements.

Field	Description
Description	Textual description of the measurement range.
Mode	Measurement mode or measurement function.
Range	Measurement range of the provision.
Prefix	SI prefix (e.g., m, k, M).
Unit	Unit of measurement (e.g., V, A, Ohm).
Range Start	Start value of the measurement range.
Range End	End value of the measurement range.
Uncertainty	Required measurement uncertainty.
Resolution	Required resolution.
Sort Order	Display order (adjustable via drag-and-drop).

Typical Workflows

• Create Provision: Define a quality provision with name and description, and add detail lines for each relevant measurement range. Detail lines can be inserted at specific positions using "Insert Before" / "Insert After".
• Assign to Procedure: Quality provisions are assigned to calibration procedures, so that the defined requirements are automatically available during calibration execution.
• Link Test Steps: Test steps can reference quality provisions to specify the required tolerances and uncertainties.

Technical Notes

Procedure Linking

Quality provisions are linked to calibration procedures via the procedure_provision table. A provision can be assigned to multiple procedures.

• The sort order of detail lines can be adjusted via drag-and-drop.
• Deleting a quality provision also removes all associated detail lines and procedure assignments (cascading).
• Access requires the permissions quality_provision_view, quality_provision_edit, or quality_provision_delete.
