Is this meter made in usa and also can it be used for household and automobile purposes.

Made in China. Klein says of the MM400: "For use in basic and controlled electromagnetic environments such as residential, business and light-industrial locations." I've used it for residential and automobile purposes.

Does it measure LoZ voltage?

MM400 does not have a LoZ function, and operating instructions are mute with respect to measuring LoZ. Klein Tools has other multimeter models that have a LoZ function.

Does it come with a case?

Mine did not come with a case, but you can order one. Look at the bottom of the listing at "frequently bought together" or something like that verbiage to show what case to order. I prefer a hard case, so I did not order the soft zipper one.

Can this multimeter test run capacitors?

Probably not, as it's high range on capacitance measurement is only 200 microfarad. Run capacitors are typically in the millifarad range for any decent sized motors, like HVAC.
