Tools and Hardware Reviews of Multimeter DT830B 19-Range DMM
Customer Review: Spend a little more money on something else
Summary: 1 Stars
I knew I was not going to get something of Fluke quality with a <$8 multimeter, but this is definitely something to watch out for.
First off the internal battery died after less than 30 seconds of having the product on. Had to remove two screws to replace the 9V battery. After doing that it has powered on, but we'll see how long it lasts. From some other reviews it appears that the battery drain on this could be pretty steep. Which would suck given how hard it is to remove a battery if you were going to leave it in a drawer for a while.
Also, there is no audible continuity tester on this despite what the manual says.
It seems that whoever is selling these are buying them from different sources and putting the same model on the label. The unit I received does not match the picture on the Amazon site. Has apparently the same features, but it's different.
Unfortunately I just needed this for basic stuff around the house and one immediate need so I paid for the overnight shipping. If it were any more money I would send it back to Amazon. But it's just not worth the time and hopefully I'll get some minimal use out of it.
If you need it for anything other than basic use of checking to see if AC or DC voltages are working then I would recommend buying something much better. Even for basic stuff I'd try something else first as there were a lot of other options within Amazon for just a few dollars more.
Customer Review: Do you feel lucky?

By buying this rubbish you're simply sending a message to whatever manufacturer in China is pumping these things out by the millions, that we're all so stupid that we'll buy anything they make if it's cheap enough.
These multi meters are sold under a myriad of brand names, and in several cases, from yellow, black, grey and red, with or with out a fancy rubber condom, for prices starting at a few dollars, up to $30 or $40. Yet they all have exactly the same circuit board. They are cheaply made junk, and verge on being dangerous.
They can be identified by the range scale, the three probe ports on the right side, and the hFE socket on the left. Regardless of brand or case colour, it's the same meter. The same rubbish circuit board, the same inaccurate dangerous junk. They are usually labeled 830B, which helps identify them.
You're measuring electricity, your life is worth more than this.
Customer Review: Very fragile multimeter. Do not drop!
Summary: 1 Stars
This meter is cute and handy, but not practical. Mine did not last one week
The ball bearings under the range selector pop out of positon, the sliding copper contacts on the selector are held in place by FRICTION, and the battery compartment contacts are the flimsiest I have ever seen. I repaired it twice, and then gave up.
Leave it on your desk at home and test batteries with it. Buy a much sturdier meter for the field.
Customer Review: No battery tester, wrong measurements
Summary: 1 Stars
I cannot recommend the multimeter, because:
(1) It has NO battery tester.
(2) The image is not identical with the real layout of the multimeter.
(3) If I do comparisons with other multimeters the measured voltages are ~15% too high -- I can only assumes my device is faulty...
Customer Review: Not worth it
Summary: 1 Stars
I was expecting something cheap, however at least it should work for simple tasks. It worked for all of 5 seconds, then died due to the discharged battery that came with it. Save your money and spend a bit more to get something that works.
