It is very possible to get an extremely large voltage back feeding into the low voltage ckt. which can destroy your VOM. There are ways of doing but in general don't - my 2cents

Yes the primary running can exceed 400 volts ! I will address diagnosis using a higher voltage scale later in this discussion . When i worked for allen testproducts our equipment would flag high primary voltage as soon as you hooked up the equipment ....
