Invalid Serial Number When Generating a Calibration Certificate

Updated Oct 23, 2023

Issue Details

I am trying to generate a calibration certificate with the Instrument Certificate Generator, but a dialog says that the serial number is invalid. I verified that the purchase was made and the serial number is valid for NI hardware. What do I do?


  1. Verify that you are using the correct serial number by reading the section Hardware Customers  in the article Finding the Serial Number of My National Instruments Product
  2. If the serial number was obtained from NI MAX and it starts with a zero, try removing the first zero.
    • NI MAX will sometimes put a zero at the beginning of a serial number as a placeholder, but it is not actually part of the serial number.
