Separate what you observed from what a record says. A dated, precise condition description gives a spectroscopy or mass-spectrometry enquiry a stronger starting point.

Questions worth settling early.
Can a service visit establish current condition?
A dated service record is useful evidence of what was addressed then. State its date and scope separately from what has been observed since; it does not by itself establish current performance.
Should I test an unfamiliar instrument for the enquiry?
No special test is needed to open an enquiry. Record what is already known and leave unverified points explicit. Any later inspection or testing should be agreed and carried out by the appropriate people.
What is a useful way to describe an intermittent fault?
Describe the symptom, approximate date and known frequency without guessing the cause. Note whether the behavior was directly observed or reported by someone else.
