Like this little meter
June 19, 2016
Bought this as a basic meter to use on job site, where I didn't want to worry about my good meter. Works just as well as my other meter and has a tone for continuity that is a big plus for an inexpensive meter.

This meter has been very useful in both Arduino related projects and other items around the house.
December 15, 2015
Cheapest multimeter I have ever seen, and works well. Nothing fancy, but most people don't need that anyway.
Good bang for the buck
February 26, 2015
For general home use this is a terrific bargain. The unit itself is small, but its LCD display is big and bright. Highly recommended.
Best value for the cost
November 29, 2014
This is good as far as the basic model functions are concerned. Best value for the money and gives a good start for beginners and amateur.
Great price point for a surprisingly accurate meter
August 24, 2016
I bought this meter to assist me while building a vacuum tube-based guitar amplifier. I'm thoroughly impressed with the meter and have used nearly every one of its functions.
A lot of cheap meters are less accurate in the triple digits. My brother is an electrical engineer, and we used his calibrated test voltage generator on this meter and another auto-ranging meter from radioshack and surprisingly both the MSR-P600 and the cheap radioshack meter successfully read within +-1v of the DC test voltage. For my purposes, that is WAY more accurate that I need. For fun, I also hooked up a cheap meter from Harbor Freight and it was off by more than 10v.
With the MSR-P600, I initially could not get the capacitance function to work. I did two things, first, read the manual, it says to push the REL button. While this zerod the display, I still couldn't get an accurate reading. Even though the meter was new, I changed the battery with a fresh one and that did the trick. I can measure caps within a second or two with 4 digits of precision. No idea how accurate the meter is, I don't have a calibrated test load.
If I was a working electrician, I would probably spring for something with a NIST certificate, but for a hobbyist, mad scientist, experimenter, or maker, I would definitely recommend this product.
And no, I was no paid to write this review.
Exactly what I was looking for
September 6, 2015
It was a tough choice. I needed a multi-meter for basic stuff around the house. I have a larger unit but it doesn't have all of the readings I wanted. When looking I didn't consider that someone made something so small. First, the packaging is NOT that horrible sealed plastic, is just comes apart, thank you! Secondly, I had no idea that it came in it's own case, another great plus. It's a nicely hinged, see through case that keeps the slim factor of the device even when in the case.
The leads are attached, which I think is required due to the small size. The screen is LARGE and easy to read. The selection knob is very straight forward with just a few options and then you can change the reading type with a button.
The really great part is the size. If you are working around the house and want to just throw this in your pocket, you're golden. You don't have to worry about breaking the leads if you keep it in the case. For the price this is a great work around the house device.
Awesome little product!
July 25, 2015
I'm the guy who usually gets the call when a family member has a problem. Last weekend my brother-in-law called and was telling me about water in the basement, coming from the area of the furnace / AC unit. I stopped at home to get a few tools and looked at my multimeter, but figured I wouldn't need it for some kind of plumbing problem. As it turned out, the problem was a faulty switch in the condensate pump, so I could have used the meter after all. The reason I didn't just grab it was it's a Fluke 77, a big all purpose multimeter. It's not a shoebox or anything, but it is big enough to take up some space in the tool bag. Also, it's just too expensive to leave sitting in the trunk just in case I need it. I decided I wanted an inexpensive little meter I could just keep with me in case the need arises. This wasn't the first time I could have used one and didn't have it.
Anyway, I did a little research on small meters. I wanted something small and light, but not missing any important functions like voltage, resistance, and an audible continuity buzzer. 95% of the time this is all that's needed. I also wanted a large display. I looked at several meters here on Amazon, and also a little Radio Shack unit I read about before I decided on this one from Etekcity. It had the functions I consider necessary, the cost was certainly right, and a lot of good reviews. I have to say I'm very happy with my choice. This thing is great!
For a little less than $20, it does voltage, resistance, capacitance, light current, and an audible continuity buzzer. If I need to measure 10 amps I'll pull out the Fluke, but most of the time all I need is to be able to check voltage or continuity. BTW, in reading the reviews here I saw mentioned at least once that this unit doesn't have a continuity buzzer. To get to that feature you go to the ohms setting and press the Select button twice. It's basically like pressing the shift key on your keyboard. That's the same way some of the other functions work, so if in doubt take a look at the manual.
I also saw a few negative comments on the leads being attached rather than detachable. I don't see how you could have detachable leads on a gadget this small. If you take a pair of regular multimeter leads and hold them alongside this little guy, you'd see that the unit would have to be over twice as thick as it is to accept them. The only other way would be some kind of custom plug, but then you wouldn't be able to easily find replacement leads anyway. I figure if the leads ever do break, I'll open this little guy up and solder in a new pair or just buy another unit. After all, this is a $20 meter, not a $500 Fluke.
One other thing worth mentioning... I had looked at the Etekcity website, and it mentioned this unit had a backlight. I couldn't find any reference to that in the manual and there's no obvious button for it, so I called them. The guy that answered the phone said there were no techs around since it was Saturday, but advised me to write an email to them and I should hear back on Monday. I know how this usually works with most companies. You send the email, and if you ever get a response it's weeks later. Not with these guys. A few hours later I got a response apologizing for any convenience, but in fact this unit does not have a backlight, and that the website had been changed to reflect that. Sure enough, they had already changed the description. I find that pretty impressive. Yes, they made a mistake, but they fixed it within hours of my pointing it out.
To sum it up, I'm so impressed with this little guy and the company that I'm about to order a couple more. One to stick in my other car's glove compartment, and one for my son. This is a quality piece of gear!
Excellent LITTLE multimeter for a great price!
July 22, 2015
First off this thing is SMALL! But...it sure does a lot! It uses a CR2032 battery (already installed) and has permanently connected leads (Not my favorite but OK). It does just about everything you can think of for around the house use or use on your vehicles and comes with a small plastic case to protect it. I tested it on house voltage and compared it to my more expensive meter. They read the same voltage, 119.9 VAC. One thing this little meter does that many others don't (at this price) is measure frequency. I was pleasantly surprised about that since I didn't know it did that. My house AC voltage frequency is 59.9 Hz which compares to my UPS display of frequency. For what this cost it is a great deal. Keep one in your car and another in your house for those odd jobs that pop up from time to time. Very pleased with this meter!
if you are like me and space is a real concern
June 18, 2015
This is one small, flat, biggest readout multimeter that I've seen. Get you one of these..if you are like me and space is a real concern..you could do worse than to get one of these VOM or by its better known name..a multimeter. What I like about it is the compactness of it and the many features it carries other than reading voltage, ohms,etc. For me and the many uses I have for a multimeter this one I can throw i my pocket and go, not have to worry about am I gonna break it or not.
The display readout is awesome, large numbers,large enough for my eyes to read it so that is sufficient for me. I have a large multifunction multimeter, that has the ammeter or amp readings, so all ya gotta do is push the button it opens a set of hands or pinchers ya stick around the wire an it will show you what kind of load you are pulling, etc. Its nice, but every time I build a coil for my E Cigarette, I don't want to have to dig that big ol honkin thing just to read what the ohm or what the sub ohm reading is. This is spot on and is accurate as my bigger multi meter.

Works well for a small home use VOM
Perfect for the science fair
July 27, 2015
My son used this for his science fair product with good success. It measured accurately for the tasks and it was repeatedly reliable. The build quality is a little on the cheaper side; however, this was to be expected for a $10 device.
January 16, 2015
Great for the money. Does everything and more for my arduino projects.
Simple and effective
July 19, 2014
If you are an electrical engineer this is probably not adequate for you, but if you occasionally need to check voltage or continuity, this does the job.
It works well enough for hobby work/diy homeowner
September 20, 2016
I like this meter because Ive still got much to learn electronically and this meter is fairly forgiving with some of its automatic functions. I also like not worrying about whether or not ive got the test leads plugged into the correct holes. The wires on this are permanently attached. Having said all that, even Ive noticed that this meter could be just a little more accurate. Its definately fine for around the house, home owner stuff and hobby work but Ive already decided that Ill need something better/more precise as I progress in my electrical intrests. So I do recomend this meter. It provides a lot for the price and simplifies things for the novice. Just dont be expecting a device fit for an electrical engineer and you should be happy.
Best on the Bench
May 30, 2016
This multimeter works well but lacks a stand or any easy way to mount it vertically. Therefore, you are forced to find a convenient flat spot to use it. I was amazed at the number of times that I could not find such a spot when using it in my car or for my hobbies. I strongly suggest that the manufacturer flatten the bottom (it is curved), add a little swing out support, or at least add an eyelet on the top so you can hang it up. It works great on a nice tidy workbench, but it is not as good as it could be when using it in the field.
I like this unit but it needs a back light so you don't have to move your head for just the right angle to see readings
May 1, 2016
This multimeter does what I needed it to do. It measures voltage, capacitance, ohms and resistance. My Heat Pump was not coming on so I called in the Costco people for a estimate on a new heat pump which they don't give you a ballpark figure in the store. The guy comes in and is asking me why I want to change out my 30 year old single heat pump. The thing is 30 years old 7 seer. He tells me 11 thousand United States dollars. I told him before I give him 11 thousand I would try to put one in myself. I don't want an edition to the house I want my air conditioning to work.
Decided to check the unit myself (basic stuff like the capacitor that regulates juice to the motor and compressor). I did not need $200 worth of multimeter so I decided on this one, under $20 which had good rating. Came in no time PRIME. I safely pulled out the capacitor (35/5 uf) and found out that I had a (0/.8 uf) no wonder things were at a standstill. Bought a new 35/5 uf from Grainger ($14) , put it into the unit, turned unit on and pipes started getting cold and cold air started a blowin.
What I think this unit needs is something to light up the readings. If you have plenty of light you are good. If the light is so so you have a hard time reading the results.
Compact and Convenient Multimeter
December 23, 2015
I am reviewing the MSR-P600 Digital Multimeter - First the unit was packaged very well, and it arrived in new undamaged condition. I was surprised at how small and compact the unit is, about the size of a deck of cards and it comes ready to use out of the box. A user information sheet was included and was clear and easy to read. The unit comes with a very convenient protective storage case which makes it easy to carry in a toolbag or technician bag without fear of being damaged. Overall I was very happy with it's appearance and ease of use. I was able to accomplish what I set out to do with this unit without difficulty. It comes with the test leads and battery pre-installed. I would definitely recommend this unit for basic testing needs. The only reason I did not give it 5 stars is the test leads are not removable as far as I can tell, so I can not comment on the durability of the leads or even if they can be replaced if they do get damaged. However, for the price paid it is an excellent value and could easily be purchased again.
It's a inexpensive meter, but don't lose the instruction book or you may have challenges
September 7, 2015
This unit is confusing to use as each setting requires you to press this and that after turning the dial to the specific spot point. Also instruction booklet is huge, not because it has a lot of information, but because it is in almost every widely used language for industrialized countries. After referencing it the 3rd time and having to flip to find the section I needed I finally pulled it out of the book and threw the rest in the garbage. (8 pages, instead of 80) The unit does come with a plastic case which is nice. If you are using it in wet weather, after you have set up the unit for what you want to measure the lead wires can run through holes at the top and bottom and the readings can be seen through the case. It isn't waterproof but it does provide some protection from dirt or the elements.

Used for science project.
December 12, 2015
Purchased for son's science project - work just fine thank you.
However, after a month, the display started to go bad - not related to battery, just started to drop portions of LCD characters.
It's inexpensive and worked fine during the time period needed, but definitely not a robust unit.
O.k/ for infrequent use.
October 12, 2014
Seems to be o.k. for amateur with infrequent use. Appears fragile, may not be suitable for use by a professional.. Biggest drawback is directions, etc. are entirely in Chinese. If you need instruction you will have to get it from the internet.

Bit light weight but it works. At this price - S'Ok
October 15, 2016
thin meter lead wires. Okay meter but a bit over rated for the price. Many feedbacks are from people getting the units free to evaluate it. Oddly enough if I got it free my option might be higher too.
I got this to test different areas of my dryer ...
August 30, 2016
I got this to test different areas of my dryer to see why it wasn't heating. I wish I would've paid a little bit more to get one with a sound feature. It would've been easier if I could've heard a tone to alert me to the fact that there was continuity in each component, as opposed to having to read the digits (not knowing what the number scale signified). This is just a personal preference, though. The devise came in a tidy little case to keep it safe and secure when I throw it in my tool box.
Item was great for a few months
May 20, 2016
Item was great for a few months. I was amazed that this tiny thing did just what I needed for most HVAC tests/repairs (minus amperage). Then... it just stopped working. Couldn't read voltage, resistance, capacitance. It only reads on DC, and it just counts up by the second.
For the $, it's OK
May 6, 2016
I found it took awhile for the readings to stabilize with this meter, in fact I had to touch the contacts more than once to get a reading at all. What I did get seemed accurate. If you need a cheap multi function meter to use around the house on occasion this one is all right. I don't think a professional would find this adequate to use daily.
January 20, 2016
It's great for checking small things at a desk maybe, but it's just too small for what I need it for. I work on refrigerators, washer machines and dryers and the test leads are just too short to check the components and be able to read the meter at the same time.

September 12, 2016
Bought this because of the great resemblance with my old Mastech M-838 (which I damaged by leaving it too close to a soldering iron).
Sienoc DT830D LCD is cheaply made. The black probe was broken (no contact). I am using it with my old probes.
The new probe wires are thinner and the plastic connector have sharp edges compared to more round and smooth edges of the old probes.
I do not like it but have no time or desire to return it and search for another one at this time. Will use it until it dies and throw it away.
If you have time to do some research and more money buy something else.
A working unit even if not so fast or accurate might provide good utility in the sub-ten-dollar range
December 26, 2015
I was excited to see if the cheapest dmm I could find would work for checking battery voltages, AC voltage, continuity, and very simple Arduino projects. Looks and feels even cheaper than expected! The unit powers on but doesn't function... no voltage readings, continuity even with leads removed. A working unit even if not so fast or accurate might provide good utility in the sub-ten-dollar range.
July 11, 2015
You get what you pay for. Simple as that.
Seems to fluctuate
April 6, 2017
Can't get a steady number regardless of the use.
I give it 2 starts for the easy of use
August 9, 2016
I give it 2 starts for the easy of use. Beside that, this product is just... junk. When turn it into DC voltage, the meter screen keeps jumping around from (-) to 50v, if you touch the 2 tips together, it slowly comes back to 0. Got my device sent back for a warranty. The replacement came back and does exact same thing.
I wouldn't recommend this product.
Easy to read and operate but the one I got didn't work.
April 18, 2016
The Etekcity MSR-P600 is a good size and seems to be made well for this price range. This display is easy to read and the device is simple to operate. Unfortunately, I received a defective device which would not take a reading. This display would count to 400 then go into negative numbers and continue. I was in a pinch, so I returned this one and bought one locally.
March 20, 2016
I bought this meter about 6 months ago. It worked fine for awhile under occasional use. Now, when I turn it on to DC volts, I get crazy readings even though the probes aren't connected to anything! The display will read 26.5, 23.3, 18.1, 46.4, and on and on. The haphazard numbers change continually about once per second.
I have owned a cheap one for years and never had any trouble with it.
cables are too thin feels like they are about to brake by just handling them
January 7, 2016
Fragile multimeter, included case is way to small to put wires back inside, cables are too thin feels like they are about to brake by just handling them, and are not replaceble. Not worth $19.99. Have a good day!

Did not meet my expectations. The iinstructions were not in English.
Recommend you buy a more expensive tool. Unit not worth even considering.
May 11, 2015
no display on dc volt. reads wall receptacle ac apparently but DCV display just goes blank and gives no reading on a 1.5 volt battery, 9 volt battery or a 12vdc CCTV transformer. Replaced unit with a recently bought a PYLE PDMT38 and all three "test" items read normally on that unit. "chimes" on continuity barely beeps.
Symptoms act like a dead battery but three different new ones,( 9.6vdc on other meter), did NOT resolve Direct Current measurement, no readout.
read other reviews, but disassembly didn't change anything.
Bought for automotive circuit repair and I've been using this type of equipment for over forty years, retired ELT.
this one is junk, I can't trust it. and the test leads are short, flimsy, don't fit the PYLE unit or any other test equipment I own.
Don't buy it
September 6, 2014
After I set the voltmeter to the 20 volt setting I used it to monitor an unusual drain on my car battery. The digital display said 6.3 volts and I thought this can't be right. So I tapped the back of the DT830D and the reading jumped to 11.1 volts. I tapped it again and the reading jumped to 12.4 volts. I don't think that I can trust this thing.
As far as shipping is concerned it was right on time. I have been too busy to return it.

Unreliable readings - don't even bother with it
October 20, 2016
I had high hopes for this little unit. The price was excellent for a meter that did all the functions I needed including capacitance. Unfortunately there appears to be nothing about this tool that is reliable.
- Registers a "phantom" voltage when the leads are not touching anything
- Resistance readings jump all over even when the leads are touching each other and the Ohms should be 0
- did a simple voltage test of a battery and the values fluctuated wildly.
- continuity test (audible) was not consistent even when there was clear continuity. it just registered a weak and uneven rattling buzz.
Basically this is a toy that I wouldn't wish on anybody trying to test anything seriously. Maybe I got a bad one and the rest are great. I don't have much tolerance for junk tools so I instantly returned it.
June 9, 2016
Appeared to be of low quality. The continuity buzzer wasn't loud enough to be heard unless held next to your ear. Needless to say, I returned it to Amazon.
