Klein Tools CL800 Digital Clamp Meter, Auto Ranging TRMS, AC/DC Volt/Current, LoZ, Continuity, Frequency, Capacitance, NCVT, Temp, More 1000V

Bought this for an RV Class and still use regularly. Well made and effective.

Bien espectacular

I wasn’t expecting a lot out of a $120 meter when I purchased this Klein CL800 but I am writing this review to tell anyone considering it that it is in my opinion the best value for your $$. I’m a Journeyman Wireman of 10 years and have used this meter off and on for the past 2 years in industrial, commercial and at home automotive work. This is a tough well built meter that provides accurate measurements even when compared to my Flukes. Also it has the most amount of different testing capabilities you can find in a clamp meter from testing capacitors and diodes all the way temperature as well as your standard Volts (A/C and DC) Amps and continuity. I have been very impressed with the quality, accuracy, and dependability of this meter. I don’t think you will be disappointed as a homeowner or commercial/industrial electrician.

I've purchased two of these. The second one due to my GSD x Malinois using it for a chew toy. The DC current clamp-on feature has been very helpful when troubleshooting automotive and machine tool power problems.I've compared the accuracy to a 6-1/2 digit Fluke bench DMM and found it surprisingly accurate compared to other low cost hand-held DMMs. I'll probably never use most of the features packed into this DMM, so many features. For electricians the low impedance voltage measurement mode is a god send by eliminating ghost voltage readings.Yes, a higher contrast display would be nice. The thermocouple measurements are a few degrees off but not terrible. In an environment with very high electrical noise it may present nonsense readings. That said only once in several years of use trouble shooting CNC machines and switch-mode power supplies did I have to switch to a Fluke hand-held DMM.Highly recommended.

De los mejores lo recomiendo

I like the CL800, don't get me wrong. It has all the features I ever wanted, and I would easily give it a 5-star rating if not for one small issue. When using the clamp in AC mode, the reading starts at zero. Not so in DC mode. First you need to press and hold the SEL button to null out the random value displayed. Only then can you measure DC current with any accuracy. WTF?The CL800 reported a normal parasitic drain of 40 milliamps (0.04 A) on my car battery with the ignition off, which is more or less what I expected. I also tested the meter with a portable DC power supply in constant volt mode (under load) and in constant current mode (shorted, with no load), and in both cases the amps it registered were in tight agreement with my power settings. So yeah, the meter measures amps in DC mode. But still...... you know....... like, duhhh.Apart from that, the CL800 is a good device, and I highly recommend it. In fact, I like it more than the equivalent Fluke. Put another way, if I had to choose only one multimeter in its class and price range, this would be it. Nevermind the odd little quirk.

This is a great meter in terms of form and function. The exterior is very durable. The plastic parts seem very sturdy and there is a rubberized coating on the sides as well as on the dial. The dial and buttons are firm and feel like they are very good quality.I'm not an electrician, I flip houses for a living. I have an occasional need for a meter to test an HVAC capacitor, the continuity of a fuse, a faulty breaker or my car's alternator. I owned a Klein MM6000 about a year ago for a very short time. It seemed like a fine meter and worked well but I was hung up on owning a Fluke as they are known to be the best in the industry. I tend to gravitate toward the best of the best when I buy anything as there is so much crap out there. Since I didn't have much of a need for a meter at the time, I returned the MM6000 and started researching Fluke to determine which one I wanted to buy. Needless to say it has been a year and I just ended up with the Klein CL800. The main reason was price. I paid $120 on Amazon for this meter and it's features are equivalent to Fluke's that cost $300-$500. I would say the features contained in this meter are closest to what you would get with a Fluke 375 or 376 which are $329 and $468 respectively. Obviously the most important thing with a meter is that it is accurate. The specs on this meter, according to the data sheets, appear to be on par with many of the clamp meters from Fluke.This meter has so many great and convenient features. First of all it is TRMS. It tests AC/DC voltage to 1000V and AC/DC amps to 600A, and also handles millivolts. It tests continuity, capacitance, diodes, resistance, frequency and temperature. It has a setting for low impedance, it has a flash light, a back light, hold button, min/max, range, and a non-contact voltage tester. The non-contact voltage tester lights a red light when there is voltage present but there is no tone and it works from approximately 6 inches from a power source such as a light switch or outlet.Some of the things I specifically like about this meter are the fact that it has one setting for volts and one setting for amps and you use the select button to switch between AC and DC. This meter will also measure millivolts but there is no extra setting. You simply set it to measure volts and it will auto range appropriately. I also like the flashlight and the non-contact voltage tester. Most of the Flukes don't have either of these features.There is nothing about this meter that I don't like. I will mention a couple of things that changed from the previous models of the Klein clamp meters to the new ones. The previous models included an audible non-contact voltage tester, slots in the rear of the meter for lead storage, the previous models included a bar graph which this one does not, and the included leads are of lower quality and do not come with alligator clips included. These features would have been nice additions to this meter but are very minor in the scope of what this meter does.I would have to say this is a great meter for only $120.

So far, so good. Still learning how to use it properly.
