- FNIRSI DMT-99 Digital Multimeter 9999 Counts TRMS, Rechargeable Auto-Ranging Volt Meter with Recording and Monitoring Data Mode, Resistance, Capacitance, Diode, Frequency, NCV, Current Voltage Tester

This thing does everything that a multimeter should do. What this sets the DMT-99 apart from other multimeters in its price range ($37 at the time of writing this review) is its digital display with the graph mode, which cycles after a little over 30 seconds, and makes it infinitely easier to diagnose those pesky intermittent parasitic drain that spikes for a second and then goes away for the next 2-3 minutes. Other multimeters in this price range lack this feature. I purchased this multimeter and combined it with a Lisle 64970 parasitic drain testing harness to test my vehicle for intermittent parasitic drain. The graph mode (shown as the "recording mode") made it a lot easier since I didn't have to keep my eyes glued to the display the entire time. It also has the ability to display minimum and maximum detected levels. The only downside is there isn't a way to scroll back to see older chart, but you can mark and save the displayed current/voltage. Fortunately, the level of parasitic drain I discovered is within the norm of a modern vehicle, but the graph mode made it extremely easy. NCV works great, and the beep is audible enough but not annoying. I was also impressed with the battery capacity. I fully charged the device and had this thing running in frigid temperature (30 to 40°F in the shade) for about 3-4 hours while performing the test, and the battery level meter only went down from a total of seven bars to six. In terms of size and weight, it's about average in its class. You can put it in your pocket, but you'll definitely notice it's in there. This multimeter is definitely worth the investment. It more than paid itself off after a single use. Even accounting for the Lisle 64970 harness, the combined cost of the two ($60) is vastly less than what mechanics charge for parasitic battery drain testing, which can range from anywhere from $120 to $200 depending on where you live.

Outstanding analyzer and multimeter. Easy instructions built toughness well designed easy setup and great for all applications and testing situations. Easy choice and fantastic price. You want the best you deserve the best so go for it you deserve this do it for you. By something you will have forever.

So. Where to begin. I broke two different flukes and I got a bit tired of shelling out $150 plus to buy a new one. Been doing this stuff for 20+ years and a meter is a daily tool. Got into a fling with aneng meters and those did not dissappoint. Got used to the auto function and with two adhesive magnet strips on the back, you can park them above the ceiling and still have both hands free. Would recommend those. Still. And then I found this one. Eh. Wow. The voltage over time read out is awesome. I can walk over to a request to exit button and walk back to the meter and it shows the voltage drop over time. That's.. well? Awesome. I dont need someone on the other end to tell me the voltage dropped. Its right there on the screen. The meter overall is as precise as one of the more expensive ones you can buy. First impressions tell me the whole thing is pretty sturdy and the leads are the same kind of quality you'd expect from a high dollar meter. The auto function works just as well as the aneng meters. Whatever you put on the leads is accurately displayed on the screen. VDC, VAC, resistance.. you name it. It is a bit slow to decide what it's looking at but that doesn't bother me. I get paid by the hour. The screen is the ultimate party trick. Whether above the ceiling in the dark or in bright sunlight. Always completely legible. Fluke should take notes when it comes to this. I also like the type C usb charger port. It charges fast and I can hook it into my vehicle charger all day. All in all. I've been in this business for quite a while. And I've probably put my hands on quite a few meters. This one truly stands out. The only thing missing is a magnet but I overcame that by using epoxy to glue a magdaddy magnet into the hanging hole. Done. For short. I don't know if it's the availability of newer IC's or cheaper screens, this is the one I'm gonna stick with for quite a while. No party tricks. Just a very useful companion for my day to day work. Try it. You won't be disappointed.

This DVM is for less professional use. Quality of the meter is reasonable (this is why the four stars), and feels a little plasticky. Do not recommend this if your are in electronics/electric on a daily basis. However for the price and what it is capable of, I can strongly recommend this for the occasional or home user. Everything works as should and meter has good accuracy. Unit is very easy to use for any user. For the price it is set I consider this good value for money.

Unknown how this meter can be purchased at this price. It is a phenominal meter in most respects, the most is its rather slow processor doing capacitor value readings on larger caps. Super for reading AC, DC, ohms without ever touching meter. Auto switching ranges and whatever you are measuring.

First this was well packaged from the factory, has a well written manual. Im looking forward to using the monitor and record features on this meter. This should help when troubleshooting an intermittent problem. The display is easy to read and seems easy to change what settings your usng. It has a rechargeable battery installed in it, which was mostly charged when it arrived. This is a fantastic value for the features it has.

Simply an amazing multimeter for people who know next to nothing about electrical systems. It's so convenient and with enough features that I expect that an expert would give it a good review (but I'm no electrical expert). The display is clear and bright, so even in darkness you can measure what you need to. The tips are sharp on the probes so it pierces to conductivity through rusty metal easily, and with handy safety plastic tip covers to keep from accidentally poking yourself when not in use. The probes easily mount to the underside of the device so that you're not dangling around a trip hazard.

This multimeter works great. I been using this for about 6 months and no issues. I highly recommend this.

Cumple perfecto con lo descrito, su modo automático te sirve para la mayoría de ocasiones, de todas formas puedes ajustar manualmente qué unidad de medida quieres tomar. También cuenta con características únicas para una herramienta de su rango de precio, tiene historial de lecturas y puedes monitorear las lecturas expresadas en gráficos. Definitivamente hay mejores pero ya estaríamos hablando de gama alta y marcas de precios altos. Por lo que cuesta no puedes encontrar un mejor multímetro, eso sí, las puntas de las terminales se perciben algo frágiles así que mucho cuidado.

I bought this to back up my main multimeter. It's USB C rechargable, the batteries last a long time and it works just like it should.

The FNIRSI DMT-99 delivers accurate and stable readings for voltage, current, resistance, and more. Auto-range and TRMS functionality add to its versatility. The rechargeable battery and data-hold/recording mode make it convenient for extended work. Good build quality and value — I recommend it for both hobbyists and professionals.

Se siente calidad, es fácil manejarlo y si eres flojo úsalo en automático... como sea, es un excelente multímetro con mediciones precisas. Principalmente lo uso en aplicaciones de electrónica y hace muy buen su trabajo, igualmente emite suficiente energía para hacer pruebas de diodo con LED's (cosa que los de dos pilas difícilmente pueden).
