Checking the converter age

The converter serial number defines the week when the converter was manufactured:
7 digits: For example, in 3260034, 3 denotes manufacturing year (2003), 26
manufacturing week and 0034 running manufacturing number.
8 digits: For example, in 14250125, 1 denotes manufacturing country (1 = Finland), 4
manufacturing year (2004), 25 manufacturing week and 0125 running manufacturing
number.
10 digits: For example, in 1173200725, 1 denotes manufacturing country, 17
manufacturing year (2017), 32 manufacturing week and 00725 running manufacturing
number.
