I trusted this exact clamp-on and replaced 2 @ $200 batteries in my Motorhome because they would only charge up to 11 volts. Turns out the meter always reads D.C. one volt short. 3 years later I forgot about that defect and replaced my generator battery but then noticed the new battery reads only 11 volts too. This meter is sitting on my desk as I type this and as soon as I post this comment I'm throwing it in the trash.

I changed my mind. I couldn't throw it away but I put it on my electronics desk to scavenge parts.

I purchased the Harbor Freight model and I think it's great.

So basically, for low voltage, low amp circuits, the CenTech is sufficient for ballpark accuracy. Excellent video. You just saved me $110. I'll get you a beer on the flipside!

These work really what really easily I suggest of anybody buys this to put the batteries in it and open the hoodie or car and try it because the first ones I bought will not work you could try right in the parking lot right on your car

Thanks for running this test and sharing it with us. This cheep meter is perfect for my very limited use, but I was concerned with accuracy. This settles it. Thanks.

A person would never use a clamp on Ammeter for true, instrumentation certified calibration at the tenth and 1/100th amp level. a few tenths off on an inductive pickup ammeter is usually close enough. Durability would be the concern that has me spending more.

Great Tips, Good Stuff 👍 Thanks!

All they’re close enough if you round up to the next number and you got the amp range and you’re good to go don’t have to have exact just go have a close in them or close enough to round it up to 10 A and Collett a day

Were you drunk when you wrote this ???

Very good comparison.

how do you use it to measure "dc" amps. the manual seemed to point that it only measured AC amps

Yes.. this meter only measures ac amps.

You will need to use all three every time and take the average - lol - Like, thanks for taking the time.

Try these when you buy this at Harbor freight try this on your car right away slip the batteries in it open your hood and give it a shot because of first ones I bought have not worked

I bought this meter and it didn't pick up a 1.5v AAA battery. It read zero volt. My other multimeter picked it up. Also, this HF meter will not do decimals when I tested my car battery which was a 12v. This meter read just 12 and my multimeter read 13.53v. That's too much of a discrepancy in my book. Unfortunately, I didn't put this meter to the test until after the 90 days return policy. I'm stuck with a useless device.

You definitely got a bad one. They measure fairly accurately if they are within spec. Not the greatest quality for sure, but it does work well when it works as designed.

Wow, they're already at 20 bucks for this thing, I thought that was cheap

Of course it's accurate or right at it because it's built by one of the big name companies in the same factory, just not got their high dollar name on it!

Your probably right.. How many factories can there be building stuff like this...

sounds like a Fluke really needed to be included

Not really!

I like videos that show every little thing and nobody’s prepared I don’t particularly like the videos where the guys do everything in the front end and then they leave out things that were kind of important that you needed to know I’d rather see it done while you’re gone and doing it get something in your head before you share it shoot the video and then you don’t let it go and you miss a lot of other things I see it on other videos all the time

What no dc amp No good for rv

Fast forward to 8:00. This is a 13min long video and 8min waste of time putting batteries in and plugging wires in. You should spend a little time prepping for your videos off camera. No credible conclusion at the end. How do you know which is most accurate? You just guessed? You should have measured the voltage across a sense resistor before the video started.

Just got this thing what a piece of crap the instructions are useless and the probes are too short to do anything with for a voltage testing this piece of s*** is going back

Good vid, but please nobody check your mains the way he did. NEVER plug your hot in first when you check outlet voltage! Serously, spray paint next to a heater? You are a walking safety violation. You must be a banker(weekend electric warrior). Nice handyman video.

Have not used that old gas furnace for years. Licensed Electrician, 40 years IBEW. In all my years learning electrical safety, I have never come accross your concern. It makes no difference from a safety concern, it's one difference in potential. How would you check a line to line load?

Safety Nazi some people are so hooked up on safety they spend all day getting ready to do one little project it takes me 10 seconds and electricians have not been taught anything that’s that important that’s over the top and you know you have an I know electricians and I know a lot about electricity myself my dad when you were young man he would say use your man hands hold onto that check that to see if that’s alive Archit and we didn’t cry and we didn’t worry about safety we sprayed spray paint with a lighter it never once blew up early the fire some people crack me up and I don’t need to be reminded of safety safety Nazi. Have you gotta worry about safety you shouldn’t be doing this project I wire lots of houses with the power on while I was doing it never once got electrocuted oh maybe once hard to be killed when there’s no ground
