Quality Lab Instrument Calibration Log

Inspection template for recording calibration dates, reference standards, results, and out-of-tolerance findings for laboratory test instruments to confirm equipment remains within calibration and supports valid test results.

Inspection Details

• Instrument ID and asset tag recorded
  Enter the unique instrument identifier, asset tag, or serial number for the device being calibrated.
• Instrument name and model recorded
  Document the instrument name, manufacturer, and model number.
• Calibration date and time recorded
  Record the date and time the calibration was performed.
• Inspector or technician name recorded
  Record the person performing or verifying the calibration.

Calibration Standard and Traceability

• Reference standard identified
  Record the calibration standard, reference device, or certified artifact used.
• Reference standard certification current
  Confirm the reference standard certification or traceability documentation is current and valid.
• Traceability to recognized standard documented
  Confirm traceability is documented to an accepted calibration hierarchy or accredited source, as applicable to the lab's quality system.
• Calibration procedure or SOP referenced
  Record the procedure, work instruction, or SOP used for the calibration.
• Environmental conditions within required range
  Confirm temperature, humidity, vibration, or other required conditions were within the calibration procedure limits during the check.

Calibration Results

• As-found condition recorded
  Document the instrument condition before adjustment, including any drift or out-of-tolerance observations.
• As-left condition recorded
  Document the final calibrated condition after adjustment or correction.
• Measured calibration result within tolerance
  Confirm the measured result is within the acceptable tolerance specified by the procedure or manufacturer.
• Calibration points verified
  Enter the number of calibration points checked during the verification.
• Measurement uncertainty documented
  Confirm measurement uncertainty was recorded when required by the calibration method or quality system.

Equipment Status and Non-Conformance

• Instrument labeled with current calibration status
  Confirm the instrument displays a current calibration label or equivalent status marking.
• Calibration due date recorded
  Record the next calibration due date or expiration date.
• Out-of-tolerance condition identified
  Indicate whether any out-of-tolerance or failed calibration condition was found.
• Affected test results assessed for impact
  Confirm any potentially affected test results were reviewed for validity and dispositioned per procedure when the instrument was out of tolerance.

Corrective Actions and Approval

• Corrective action documented for any failure
  Describe repairs, adjustments, retesting, quarantine, or other corrective actions taken for failed or out-of-tolerance items.
• Supervisor or quality reviewer approval
  Signature of the reviewer approving the calibration record and any required follow-up.
• Calibration record complete and legible
  Confirm the record is complete, legible, and suitable for audit review.
