Klein Tools 400A AC Auto-Ranging Digital Clamp Meter is rated 4.5 out of 5 by 24.
Rated 5 out of 5 by from An Excellent Value I have two other more expensive clamp meters and the Klein CL330 held up very well in comparison with them. I verified that the accuracy of all functions was within specification, usually much closer than the tolerances allowed. This meter has many features not normally found in this price range - an OLED display that can be easily read in many lighting conditions and off-angle, the ability to capture min/max/ave readings for all functions, a carrying case with belt loop, a low 4A range setting for increased resolution, temperature sensor, capacitance range from 10pF to 4F, and HZ measurements to 1MHz. The meter can be used with one hand. I could easily reach all the controls using either my left or right hand alone. Be default it will automatically turn off after 10 minutes but that can be disabled. This meter doesn't measure DC current at all, and only measures AC current using the clamp, not the leads. It has a non-defeatable beep when functions are changed that I found slightly annoying.

Rated 4 out of 5 by from Product seems to work very well. I have a fluke that I had for the last 30 years and it serves me... Product seems to work very well. I have a fluke that I had for the last 30 years and it serves me well for Automotive applications but this one has a few features that the fluke does not have. Hopefully it will hold as long! First impression is it looks to be well made and the screen is easy to read in all light situations. I give it a 4 rating because it looks good and for the price I paid it seems like a very good deal, but time will tell if the clamps hold up, they seem to be a little damage prone.

Rated 5 out of 5 by from Well Built and accurate. For this price range, I believe you are getting a lot of tool for your money. This Klein digital clamp meter is good quality and accurate. The clamp tests some functions, while others are from the leads that plug into the bottom of the unit. It comes with the different leads that are of a nice length needed to run the many tests that it does do. Also includes a thermocouple, case and batteries as well. The OLED screen is easy to read from any angle, and is bright enough for many lighting conditions. The case of the meter is solid, and it feels good in the hand. I was able to operate with one hand for everything I was testing with it.

Rated 5 out of 5 by from Very nice Klein CL330 400A Auto-Ranging Digital Clamp Meter. This is a very capable Meter very good OLED display. Well packaged with test leads, thermocouple, pouch and batteries. The clamp opens enough for easy wire measurements. Cat lll safety rating high impact plastic construction and feels good in your hand. The thermocouple is a little on the cheap side but is functional . This Meter has many functions to handle most electrical need from basic line voltage to Diode and capacitance tests . With auto Range it will do the basics for you. The data hold and audible continuity is also very helpful . The frequency duty cycle works well. AC,DC,AC CURRENT, DC MILLIVOLTS this Meter can do It all. In comparison to my very expensive Fluke the values are right on. I do love the display too. Another good tool for my everyday tool bag.

Rated 5 out of 5 by from Easy To Use And Super Easy To Read Finally, a meter that’s easy to read in all conditions. The screen is clear and bright with three brightness settings. No more struggling to get the screen in the right position to get a clear view of the readout. This Meter is about two thirds the size of other Clamp Meters and yet it offers all the features of the larger units and more. This unit is only 9" x 2.5" x 1.5" thick and weighs in at only 11 ounces. Also, the meter has most of the more common tests of a multimeter. From simple voltage tests thru measuring cycles per second, in circuit diode and capacitor tests. The meter even comes with a fast reading temperature probe. Since this meter is smaller it is very easy to operate with just one hand. The test selector dial and hold button are easy reach and use with just your thumb. The clamp lever is placed where your index finger lands on the meter to make opening the clamp easy. The meter does have an auto shut off after about 15 minutes of inactivity. The longer time limit before auto shutdown is nice since it gives plenty of time to accomplish longer tests and setups. The meter comes with a set of removable red and black probes that have removable high voltage tip shields. Also supplied, a nice zippered storage pouch to keep everything in one handy place. This is a very nice meter, that will do almost any test that are commonly needed. Its smaller, light weight and the readout is bright and large even in direct sunlight. Overall this meter is easy to use, very accurate and affordable. If you're looking for one main meter this is one to consider.
