"Inductive" ammeters only work on alternating current.

To measure DC flows, you need either an in-line ammeter, or a 
Hall-effect clamp-on meter.

I mention this because Hall-effect clamp-on meters are quite a bit more 
expensive than the simple inductive (aka "current transformer") type.  
It needs to say "DC" somewhere on the meter or the package.
