What does the auditor look for in the scale documents?

This is the trust story ,One customer told the TMC team after the audit that
“The scale has already been calibrated.
But the auditor kept asking so many more questions that the QA team was caught off guard.”

From the experience that our team has encountered repeatedly,
The auditor doesn't just look at the calibration sheet.
but looks at the “readiness of the entire system of documents.”

And we have already summarized that this is the key point that the auditor actually focuses on. 

 The reconciliation statement… to be honest, it's not enough to just have it. It has to be correct.
Because many customers have all the certificates.
But the auditor will look in detail to see if:
- Has the calibration certificate expired?
- Does the device number match the actual device in use?
- Is it issued by a reliable laboratory?

From our team's regular experience, we have found that sometimes the documents are complete, but if any details do not match, they are immediately questioned.

 After verification, “Does it cover the actual use?”
The auditor often asks further:
“What are the operating coordinates of this machine?”
Then they will open the Scope for comparison
to see if it covers the actual weight range used.

This is where many factories often make mistakes because they have already performed the calibration
but it's outside the scope of use.

 Traceability is more important than you think.
Based on our experience, TMC would like to say that the auditor does not ask difficult technical questions.
but they will check whether the calibration results can be traced back to the reference standard.

If the documents are not clearly explained, the QA will immediately turn pale and find it difficult to answer questions.

 Is there continuous control or is it done only during the calibration period (Audit)?
Another common question is:
“When was this instrument last calibrated?”

The auditor wants to see the calibration history to confirm that the organization actually controls the instruments, not just calibrates them when the audit is approaching.

Therefore, based on the experience of the TMC team, which provides advice and performs calibration of weighing instruments and measuring instruments for many industries, the audit does not look at whether the weighing instrument has been 'calibrated yet', but rather at how well the organization 'understands, cares for, and controls these weighing instruments and measuring instruments'.
Because if the documents are clear and can answer the questions, it helps the audit day go more smoothly.

If any organization needs to verify the accuracy of weighing instruments and measuring instruments to ensure the highest quality of products, as well as to prepare for an audit, they can contact Thai Metrology Calibration Co., Ltd. (TMC). We are an ISO/IEC 17025 accredited laboratory.
