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. ## Frequently Bought Together - Klein Tools MM400 Multimeter, Digital Auto Ranging, AC/DC Voltage, Current, Capacitance, Frequency, Duty-Cycle, Diode, Continuity, Temp 600V - KingSung Hard Case Compatible with Klein Tools MM400/MM300/MM200/ET140/MM720 Digital Multimeter (Only Case), 1 Pack - Klein Tools 69381 Alligator Clip Test Leads, Heavy-Duty Replacement Meter Leads, for All Meters Using Banana Plug Meter Leads, 3-Foot --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/742405609-kleintools-mm400-digital-multimeter-auto-range-600v](https://www.desertcart.be/products/742405609-kleintools-mm400-digital-multimeter-auto-range-600v) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-26*
