Thank you for the positive feedback, much appreciated.

Thank you for the feedback. It nice to hear the video was helpful. It can be a challenge to detail the features of a digital multi-meter without overwhelming the viewer.

@@cfldriven That is exactly why I commented. I sincerely appreciate the time and effort (not to mention skill) that goes into producing a video that allows a novice to understand a product. I put together a 40 gallon parts washer with multiple upgrades and would like to make a video for others to see in the event that someone can benefit from my time, effort, and research on the topic. However, the challenge of producing a clear, complete, concise video on the topic is something that I find daunting at a minimum. So, when I see a video such as yours on a topic that is important to me I feel compelled to let the person know that their efforts were sincerely appreciated. On my best day I would not have the skill to duplicate what went into your video. Kudos, sir.

@@bowalle7623 Thank you, I'm sure not all my videos are clear in concise, but I use viewer feedback to fine tune what I miss. Make your video, show it to friends and listen to their feedback. It always a learning process. Best of luck to you.

Alfredo, we try, thank you for watching and the kind words.

Congrats on the meter. In the continuity mode the device provides very small amount of power to circuit and if detected you hear the tone. It not meant to operate with the circuit energized. Same with Ohms mode. Best to decide what is it you want to measure, determine whether the circuit needs to be energized, set the dial, and take a measurement. Thanks for watching.

Ruben, the only thing I don't like about this meter is the probe connections on the bottom can easily come loose and give false readings, especially when it is hanging. I also have the CL390 which I like a lot and doesn't have the probe issue.

Dave, thank you for sharing your insight.

The CL440 will read up to 600 amps AC only. While the CL390 will read up to 400 amps AC and DC. The magnetic holder is optional, although like you I feel it should be included.

I wanted to read both AC and DC current, the CL 440 is AC current only so I bought the CL390 which does AC and DC current and is cheaper. I find for residential use the CL390 is plenty of meter. If you work with motors the CL440 is worth considering and if you need something that is water resistant, that has a work light, higher AC/DC voltage and tougher build than the CL 800 is worth considering.

I have the CL390 and CL440 and they are both capable of testing capacitors. The CL390 lets you measure both DC and AC current along with being smaller in size. I wanted to get an Ideal to compare, but never got around to it.

Mojtaba, thank you for watching.

It can read and display from 600 ohms to 60 Mega ohms.

Yes by setting the dial to Hz% and clamping around the positive or negative, but not both, it will give you Hertz reading.

@@cfldriven positive or negative? Hz means you're measuring AC.

​@@r.t.7925 Wow did I actually write that? The clamp is for reading amps from either the positive or negative wire but not both. To read Hertz the probes are utilized. Thank you for pointing out my error.

Thanks to r.t.7925 for putting out my error. The clamp is for reading amps from either the positive or negative wire but not both. To read Hertz the probes are utilized.

@@cfldriven On this particular meter clamps only measure AC current. You will not get reading if you clamp positive or negative wire . You'll get a reading if you clamp one wire that carries AC current. You can't measure DC current with the clamp is what I'm trying to explain.

All depends on what you are looking for. The CL450 has two temp probes but less of a temp range. CL450 can read up to 1000V AC/DC, beating the CL440 750V AC & 600V DC. Both do 600A AC only, while CL440 can read up to 600 DC microamps and the other stops at 200 DC microamps. In many ways they are similar unless you need a specific parameter. Also the CL450 is no longer in production. Thanks for the question and watching.

The reason not to do it is to eliminate any potential electrical paths. The same reason you're also suppose to wear insulated gloves and eye protection. Of course in the field people will decide the amount of risk they are willing to accept.

@@cfldriven OK, that answers part 1 of the question. What about part 2? If it's unsafe or inaccurate, what's the point of building in a setting where you are *required* to operate in a "non recommended" way to use that feature? Even the user manual contradicts itself on this issue.

@@realSamAndrew I don't know for certain but I suspect when set in the V + A mode a special circuit is being utilized, otherwise the manual states not to leave the probe inserted when measuring with the clamp.
