Hi all,
I?m new guy for working with calibration laboratory. Now I have a question to enquiry expert to solve my problem.
The question is that, we have a calibrator for external calibration in each of year. It?s calibrated by Manufacturer (Lab A). Now, due to the cost problem, we have selected another Lab B for doing calibration on this year. After calibration from Lab B, they points out some of test point were out of manufacturer?s stated 1-year relative accuracy limits. However, Lab A was no problem in the past.
Does anyone know what the problem here is? Both lab A and B are accreditation laboratory. Why their result has such as big difference? How can we judge which lab has problem?
Thanks.
