It seems that the version DT-830 with the separate on/off switch is different then the version without this switch. i have here a unbranded version for doing low voltage measurings etc, bought e few years ago in a sort of dollarstore, and this week one part of the LCD screen didn't work properly, so i took it apart and cleaned the zebra rubber strip and it was back up and running. To my surprise had this meter 2 fuses and a PTC. One 500mA fuse for the mA range, and a 5A fuse for the 5A range. I have also some older versions of this meter from back in the 90's, and if i remember correctly, they didn't had any fuse back then, and one of these models has even a flashlight build in on top of the meter, with a on/off switch on the side of the meter.

Thanks for your "research and testing" of all of those meters and prior ones too. Great resource.

Great to see you back! Interesting how the sparks traveled inside and outside the meter case!

Nice Video Joe. ❤

Great experiment, Joe! I have been following the discussion at EEV and I was going to reply to that thread - unfortunately my time has been quite scant to participate on the forum lately. Another M830B- type meter worth testing is the Hypertough (sold at Walmart), which has third party certification. In the tests I did on my channel (280Vac) it performed quite well and was undamaged in all ranges (except battery testing, but that was expected due to the load resistor). Sure, it wasn't 2kV but it was within its own spec (300V CAT I).

I want the Walmart hypertough tested too.

Well, good experiment. Thank you!

Your 2 supplies one high, one low voltage. Just like the way an arc is established by a TIG welder

True.

I wonder how many of these things are given to children as toys?

It's about as good as my first Fluke meter. I would have liked to have had a few of these growing up.

@@joesmith-je3tq oh yes first multi meter I had was 1kohm per volt , my first digital was a broken autoranging HP .it had a burned out analogue switch ic (hp special , they quoted something north of £700 for a replacement, so I made one with half a dozen cmos chips and two boards sandwiched together - it mostly worked) . Yes would have killed for one of those freebies:-)

This is a new level of shoddiness. 250V DC can be easily exceeded by probing around household items, in europe rectified mains is 324V DC, in the US interphase voltage between two lives can be easily 240 or 480VAC. Thats dangerous to give out to untrained people.

I doubt you are suggesting we need to regulate the sale of DMMs. Untrained people should avoid dangerous environments and trained people should use proper tools for the job. Many meters I have looked at do not use safety fuses , or no fuse at all like this one. We could regulate the import of such products but then again, I saw on a popular channel where the person was going on and on about safety and Fluke meters, all the while showing that they had blown the fuse and replaced it with something from the local hardware store.

@@ItsBoyRed I don't think that's any big secrete. AGV or something another. They did a review on a Fluke non-contact meter. I was asked to look at it and watched some of his other videos on multimeters. One was on Fluke vs some low end meter. This video provided a clear image of the fuse I mentioned. I've posted about it on EEVBLOG and I may have included a segment in one of my videos. Shouldn't be too difficult to find.
