concur with FE.
The pilot is ordinarily obliged to give access to the aircraft, and to show documentation as necessary, but any test that is not part of routine operations, or is not in the supplemental procedures section of the POM/FCOM should not be undertaken by the pilots for the inspector.
The courteous answer is that you are not authorised to conduct such a check, so need to get an authorised person to conduct it, at the request of the inspector.
Be aware also, that an inspector is required to show an ID (and for the FAA a badge nowdays), on a ramp check, and they have been known to swap ID's between 2 inspectors, and then fine the operator for failure to check. As it is a civil penalty, under USC 49, each event is a max fine of 10K, ie 20K fine just for acquiescing to their presence without checking docs. The same argument could be made for conducting a test thast you are not licensed to undertake, so beware.
Majority of EU SAFA inspections are (IMHO) rational, and comply with the checklist and standards of:

Be aware that in the USA, security can become a USC TITLE 18 crimes issue really fast... a foreign carrier travelling to or from the USA has a US jurisdition imposed from these regs, which takes things into the serious mode... additionally, a case reviewed in 2006 concludes that the US bill of rights, doesn't have to apply to foreigners. That was upheld in review, and so any visitor may be fairly exposed ie, no 4th or 5th ammendment rights...
