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 MM450 Slim Digital Multimeter, Reverse Contrast Display with Lead Alert, Auto-Ranging TRMS, 600V AC/DC Voltage, Current, Resistance, Temp, Frequency, Continuity - Klein Tools 69417 Rare-Earth Magnetic Hanger, with Strap - Klein Tools 69381 Alligator Clip Test Leads, Heavy-Duty Banana Plug Replacement 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.ni/products/468635703-klein-tools-mm450-slim-digital-multimeter-reverse-contrast-display-lead](https://www.desertcart.ni/products/468635703-klein-tools-mm450-slim-digital-multimeter-reverse-contrast-display-lead) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-07-21*
