How to render values of fields in the appropriate language?

I made a content type programmatically with entity translation module. There are about 250 fields.

240 fields are not to translate because there values are identical.

So I only want to use entity translation for about 10 fields.

Now i have a lot of checkboxes and select fields. This are all associative arrays. Out of the box the values are shown in English for german and english urls.

E.g.: Select list: ("keyA" =>''valueA", "keyB"=>"valueB") shows "valueA" or "valueB" as result of the node.
I want t function included to use a po file for translation.
Thus t('valueA') has to be implemented befor renderring the field?

How can I do this?

THX in advance,
