Klein Tools CL120 Digital Clamp Meter, Auto-Ranging 400 Amp AC, AC/DC Voltage, Resistance, Continuity, Non-Contact Voltage Tester Detection

Klein Tools CL120 Digital Clamp Meter, Auto-Ranging 400 Amp AC, AC/DC Voltage, Resistance, Continuity, Non-Contact Voltage Tester Detection

Q: How high of voltage will it test ?

The included paperwork says 600 Volt. 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?

Yes. 3 decimal points after whole volts. I.e.; 1.419 volts for a AA battery

Q: Is a case furnished with the meter?

My CL-120 cane with a fabric zip case

Good meter that worked out of the box.

It is an inexpensive meter for the do it yourself person. It works fine. Also it has no Capacitive reading functions on model CL120. If you buy this to test AC Current I reccomend buying the cord separator from klein tools to test ac current in a cord. That option is very handy to have. The NCV test that checks for powered circuits by touching the meter to it works better than that device they sell to test for AC Power! Thanks.....From a retired Tech.
