It's very easy to do by yourself, just prepare a set of test equipment, and the most important is that you must send the meter to be calibrated...

Normally, it's for UL Type 4X test, from UL's side, they wanna use the manufacturer's equipment and witness this test in the field, what I know, at least in Jiangsu province, it seems like there is no lab which can do this test...
