Review: Graph mode allows for easy testing of automotive parasitic drain - 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.
Review: Nice meter, easy to use, not alot of money - 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.

## Features

- 【Recording Mode】FNIRSI multimeter can plot measured value ripple that changes over time is drawn, and the fluctuation of voltage or current over time can be observed. 8 measured values can be recorded, and the Max and Min measurement values are displayed
- 【Monitoring mode】Custom thresholds can be set in multimeter monitoring mode, and a warning will be issued if the voltage exceeds or falls below the set threshold
- 【Solving hunger】Built-in 1500 mAh rechargeable battery allows the multimeter tester to work longer. No more manually replacing bulky, unfindable disposable batteries, the Type-c port renews energy at any time
- 【Intelligent Mode】In intelligent mode, DMT-99 digital multimeter can identify the measurement content and select the range with the best resolution, making the measurement more convenient and faster,Takes out the guesswork for most applications
- 【Private customization】2.4-inch full-color TFT screen display, 240*320 resolution, makes it easy to use in dimly light areas. Supports DIY startup interface and creates your own personal entry interface
- 【Intelligent Multimeter】It measures AC/DC voltage, AC/DC current, and can be used to test resistance, capacitance, continuity, diode, NCV and live wire etc. Applicable to automotive, home appliances, other electronic repair. Dual ceramic fuse protection

### ⭐⭐⭐⭐ TPS glitch ahh no. Glow plug relay volt drop, alternator output, current inrush, oh yeah
*by N***E on November 22, 2025*

Like the meter, especially the graphing, that is what i use mostly for DCV. the continuity beep is fairly loud, for 5 feet, quiet for 10 feet in a noisy shop. A separate enter and back button would make 1 hand meter selection much easier. This price point i can live with it, at least it isn't just a mode/select button. Will buy another when needed.
