@Wolframore, congratulations on your purchase!
The ultra low cost meters are quite bad in terms of CAT ratings, but the midrange Chinese ones seem to be at least marginally well made.
Since the standards aim the survivability and safety of the operator and not the equipment, @joeqsmith's tests certainly fill this gap up to a certain extent.
That said, I don't really see how Gossen could get away with such susceptible meter - maybe the standards do not evaluate for magnetic interference? I know that electromagnetic fields are tested. Well, that or they are cutting costs during production (after the unit passes certification) - their silence after @joeqsmith's messages really gives a lot of margin for speculation. Despite Gossen is a household name, it may have been under the influence of the bean counters (nobody is immune to them, really). Even Fluke has been taking measures to cut costs, but it seems they are years ahead in well designed products.
