Free Equipment Calibration Log Template

A calibration register for tracking measuring and monitoring equipment: equipment ID and description, calibration standard and traceability, interval, last and next due date, as-found/as-left results, and the out-of-tolerance (OOT) handling procedure. Built to support ISO 9001, AS9100, IATF 16949, and ISO 17025-traceable calibration programs. Generated instantly, no login required.

How to use this template

  1. List every piece of M&TE in scope — measuring and test equipment used to accept product or verify a process. Assign a unique equipment ID to each item.
  2. Set the calibration interval — based on manufacturer recommendation, usage frequency, and drift history. Record the interval and calculate the next due date from the last calibration.
  3. Record as-found and as-left readings — every calibration event, log the as-found condition (before adjustment) and as-left condition (after adjustment) against the reference standard.
  4. Flag out-of-tolerance (OOT) conditions — if as-found readings are outside tolerance, open an OOT investigation to assess impact on product measured since the last good calibration.
  5. Record traceability — note the calibration standard used and its traceability to a national metrology institute (e.g. NIST) or an ISO 17025-accredited lab.
  6. Post or file for audit — keep the log current and accessible; auditors will check equipment calibration stickers against this log during process audits.

Calibration Note: If a gauge is found out of tolerance, the impact isn't limited to that calibration event — you must assess every measurement taken with that gauge since its last known-good calibration and determine whether affected product needs to be re-verified.

Frequently asked questions

What equipment needs to be on a calibration log?

Any measuring and test equipment (M&TE) used to accept or reject product, or to verify that a process is in control — calipers, micrometers, torque wrenches, gauges, scales, thermocouples, and similar instruments. Equipment used only for reference, not acceptance decisions, is typically excluded.

How do I set a calibration interval?

Start with the manufacturer's recommended interval, then adjust based on usage frequency, environment, and observed drift history. Equipment that repeatedly comes back in tolerance can often move to a longer interval; equipment that drifts should be shortened.

What is 'as-found' vs 'as-left'?

As-found is the reading measured before any adjustment is made during calibration — it tells you whether the equipment was accurate throughout its use since the last calibration. As-left is the reading after adjustment, confirming the equipment leaves calibration within tolerance.

What do I do if a gauge is found out of tolerance?

Open an out-of-tolerance (OOT) investigation. Identify every measurement or acceptance decision made with that gauge since its last known-good calibration, assess whether affected product is still conforming, and disposition accordingly — this is required under ISO 9001, AS9100, and IATF 16949.
