Measurement stability declaration for power meter

[Stuart_Cheng]

Hi All,

I received some inquiries about calibration-free statements of our power meter. Since all of these statements are self-declarations, my customer is doubtful about this.

Wondering any idea the declarations are based on which standard and do other competitors also provide this kind of statement? What is the major difference that Schneider is confident to provide this kind of statement and how do we usually convince our customer?

Thanks
