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. ## 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.
