VYRCOWho it is for and what is included
Mold, machining, quality and metrology technicians.
Level: Intermediate. Includes instructions, recording fields, a fictional example and reference sources.
How to use it
- Job defined: Correct drawing and revision; feature, units, requirement and decision authority identified.
- Instrument identified: ID and model match the applicable record; status and restrictions are available.
- Method justified: Range, resolution, method and applicable criterion are documented rather than inferred from display digits.
- Preparation and check: Visible condition, preparation and authorized checks are recorded according to the manual and procedure.
- Close before measuring: Questions, restrictions and open items have an owner; the decision and link to the dimensional record are documented.
Fictional example
FICTIONAL: DEMO-INSERT-A requires an outside measurement. DEMO-MIC-01 has a legible label, but the available record belongs to DEMO-MIC-02. Status: PENDING. Record the mismatch and request the correct record; do not conclude that the instrument measures incorrectly.
Scope and limitations
Does not calibrate or certify an instrument and does not release parts. Prescribes no tolerances, maximum uncertainty, resolution-to-tolerance ratio, interval or universal condition. The drawing, manufacturer manual and authorized procedure take precedence. A zero setting alone does not demonstrate performance across the full range.

Traceability belongs to a result and does not, by itself, demonstrate fitness for use. It supplies no numerical criterion for this template. - Mitutoyo - Quick Guide to Precision Measuring Instruments
Micrometer-specific context: selection, thermal preparation and care of measuring faces. It does not replace the actual model manual. - JCGM - VIM3: calibration
Conceptual distinction between calibration, adjustment and verification; not a calibration procedure. - JCGM - VIM3: verification
Verification requires evidence against specified requirements. It provides no acceptance requirements for a particular instrument. - JCGM - VIM3: adjustment
Adjustment changes system indications. It authorizes neither adjustment nor substitution for calibration.
