Calibration log
Inspection logWhen it was done, against what reference, and by whom.
The fact of it, and against what
Who did it, when, against what reference, what it read before adjustment and what was adjusted. Those five facts are the whole of an honest calibration record kept by a user.
No interval and no claim
Intervals differ by instrument, by use and by specification. Accuracy is the calibrating body's statement, not this log's.
Around it
Lifting gear is the lifting gear inspection log. What is on hire is the equipment hire register.
A record that an instrument was calibrated or checked. It performs no calibration, supplies no interval, claims no accuracy and asserts no traceability. Everything runs on your device.
Questions people ask
- How often should an instrument be calibrated?
- This product supplies no interval. It comes from the manufacturer, from your quality system and from whoever specifies the work you are doing with the instrument. There is a field for the date somebody gave you, labeled as a date a person set.
- Does it claim the instrument is accurate?
- No. No accuracy, uncertainty or tolerance is claimed anywhere in it. It records that a calibration or check happened, and what it was checked against.
- Is the calibration traceable?
- Nothing here asserts traceability to any national or international standard. Traceability is a property of the calibrating body's own certificate, not of a log that mentions it.
- Does the tool calibrate anything?
- No. It performs no calibration and verifies none. It is a record that somebody else did, with the as-found condition written down before anything was adjusted.
