All Mi3 heads (except some specials) have end test performance data embedded in them at the point of final verfication during the automated manufacturing calibration process.
The data is easy to extract and print and is provides useful confirmation of performance without need to specify an additional calibration certificate (unless you need a fully traceable document).
You will need to run and install DTMD v5.4.1 and ensure that the VCOM USB driver is installed
