I have measurement equpment to measure resistancy. can I calibrate it using corelation parameters, entering certain value of electricity flow (in ampere). If I can, any body knows the procedure ? Help me and I am sorry about my English.

I cannot personally help you on this question. Hopefully someone else who visits here can. But - just in case, you might also want to post your question on the calibration listserve.

Dear Greg

I am Iim Ibrohim from Indonesia. I know your name from Marc at the Cove. He told me that you can help my problem.

We have a measurement equipment to measure resistancy of potentio meter (in ohm). Actually it is like an attribute measurement aquipment. We set the limit, and it become a go no go gage. The question is, if we do calibration by feeding certain value of Ampere, will it be a problem (in the relationship with ISO guide 25 or QS-9000) ?

If we can do it, is there any procedure or guidance you can send to me ?

Thank's in advance.

Moderator Note:

Iim,

It sounds like you are using a pot (or linear pot) to measure a distance
or rotation. Using the measured ohms you are converting it to a go-nogo
tester.

Neither ISO25 or ISO900x will argue with you as long as;
- The equipment is calibrated and traceable.
- Your method is preferrably published or custom.
- This method will have to be agreeable with the client
- Most importantly you have evidence that your device produces values
within the tolerance and uncertainties required by the go-nogo criteria.

Greg
