Validating Electrical Tester

[RubyFox]

At our site we have an electrical tester that can't be calibrated in this country. We want to validate that it is measuring results that are acceptable for our process. We do have several pieces of calibrated equipment that can replicate the tests, but I'm not sure how to use that information. I know what I would do to prove to myself that the equipment is working, but I'm struggling with how to prove it following automotive standards.

Suppose I had measurements from both methods and all the values were the same within the equipment's expected variation. Is that enough to say the tester is good? I would love to do a large study to validate this, but even getting 6 parts set aside for an hour will be a tall order here.

What standard applies to your work? What does that standard say you can do?

I've had measuring equipment that could not be calibrated by anyone, but I had a verification method that my customers accepted.

ISO90001 and IATF 16949 as general to the plant. The test itself has a standard that is in process. Engineering is still making it and working out the kinks. So the test is effectively being done as a process control at the moment and to give engineering data. By that logic we should be able to say "we are doing X to verify the tester please approve this" get customer buy off and be done.
