That’s kind of an industrywide cut off point between “normal“ power versus what is generally considered to be high voltage. I would feel comfortable using it to test 480 V all day long. I would not use it over 600 V under any circumstances. **Q: Does it measure volts in millivolts in DC? How many digits does it show after the decimal?** A: Yes. 3 decimal points after whole volts. I.e.; 1.419 volts for a AA battery **Q: Is a case furnished with the meter?** A: My CL-120 cane with a fabric zip case **Q: Does this meter come with a calibration certificate?** A: Mine did not. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Happy *by T***S on September 3, 2026* 1 meter does it all auto off 👍👍 easy read screen 👍👍 I wish case was larger for my longer test leads ### ⭐⭐⭐⭐⭐ Dependable and durable. *by M***. on July 28, 2026* Good tool. You can’t go wrong with a Klein tool. Always have been dependable and durable for me. ### ⭐⭐⭐⭐⭐ Quality made and reasonably priced for a brand name. *by T***X on October 15, 2025* So far, this is a quality made durable tool. I'm not an electrician, but I am capable of household and automotive electrical repairs. This tool is reasonablely easy to use and I like that it holds one of the probes in a clamp on its side. I cannot report it's accuracy, but I am confident that it's function is as well made as it's exterior. Even the case appears to be well made. It's kind of big because of the clamp, but it fits in my tool bag just fine and the price was reasonable for a brand name product. I have another more expensive volt meter, but I like the Klein better because it has a flat screen.. Even with the back light on, the curved screen on the other tester I own I finger difficult to read. ## Frequently Bought Together - Klein Tools CL120 Digital Clamp Meter, Auto-Ranging 400 Amp AC, AC/DC Voltage, Resistance, Continuity, Non-Contact Voltage Tester Detection - Klein Tools 80016 Circuit Breaker Finder Tool Kit with Accessories, 2-Piece Set, Includes Cat.
