Hi !

Can anybody have idea about how to find date of manufacturing of v20 vfd from serial number.

If know pls help me in finding..

It goes like this: SZV......

S is for Siemens

ZV is the productions site identifier (SNC)

Next two letters are Year and Month code

For year: A is 2010, B is 2011, C is 2012 and so on, but without a G (ABCDEFHJ)

Month is easier, 1 - Jan, 2 - Feb and so on, 0 is October, N - Nov, D - Dec
