This is not so much a mistranslation as use of an older meaning of "prove" still is use in such terms as "proving ground" and "proof sprit". In this sense "proof" means "make sure that ... is up to standard". If a certain proportion of gunpowder added to a spirit would burn, that was "proof" that there was not too much water in it.

This is a good example of the older meaning.
