## Questions & Answers

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

**Q: Does it measure LoZ voltage?**
A: 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.

**Q: Does it come with a case?**
A: 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.

**Q: Can this multimeter test run capacitors?**
A: 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.
