To demonstrate compliance with your program’s QAP it is best to keep a record or a Calibration Log for each device used for testing. The log should contain the results of all accuracy checks and calibrations for each instrument. This log may become a crucial piece of evidence should your test results be challenged. The log may include information such as:
- Date
- Time
- Procedure performed (Accuracy Check or Calibration)
- Name of Technician performing procedure
- Location
- Identification of the Standard including Lot Number of the Standard
- Expected Value of the Standard
- Result of the Accuracy Check or Calibration
