I found a very strange phenomenon when buying instruments now, especially domestic ones
They all need to be adjusted by the measurement department, instead of being qualified before leaving the factory, while foreign instruments are all labeled What does the annual stability mean?
You said it is necessary for the national metrology to be adjusted simultaneously, but I said he should issue you an unqualified certificate!
Excuse me, if it is not qualified, are the products you produced before qualified?
In addition, the measurement department has made adjustments for you. People who buy your products will say that my machine is qualified, but in fact? The data made before are all fake!
It can be seen from the results you added that the testing machine was produced by you. I would like to ask why it failed to pass the factory and you did not debug it before measuring it at the installation site? Isn't there even a standard device?
Following further investigation, does your company’s testing machine have a measuring instrument production license, and do its employees hold the license to work? Debugging is not allowed. Please learn our country's measurement laws before posting such a post.
