FNIRSI 2C53T Upgraded Handheld Oscilloscope, 50MHz Bandwidth, 3IN1 Digital Oscilloscope Multimeter DDS Generator, 250MS/s Sampling Rate, 19999 Counts, Voltage, Current, Capacitor, Resistor, Diode Test

I like this. It's practical and easy to figure out and use. I purchased it because I use the Oscilloscope and Signal Generator. A great price too. A few years back something like this would have cost a fortune. It's Professional quality and comes with the both signal and test probes. It does a lot more. Im still learning more about it.

Great value.Used the meter, scope and signal generator when installing a car stereo.Not much bigger than my stand-alone multimeterThere's a bit of a learning curve to master the Oscilloscope menusBattery lasts a long time - used it for several hours on its initial charge before needing to rechargeSeems well-built and durable with rubber cushioning

Its a great tool and its pretty compact. I like that it comes with a nice case and some decent probes. Its pretty accurate and has really good functions for its money. However, sometimes the frequency it tells you a wave form is, can be a little bit off and sometimes the timebase affects it for some reason. I also wish the display was rolling. On bigger timebases, it loads the waveforms more slowly left to right, writing over the previous ones, rather than having them roll on screen from right to left, and that really sucks, but other than that it was worth my money. The trigger is also a little funny, and doesnt always do well. sometimes i can get it to work perfectly by adjusting the timebase and/or the voltage sensitivty.

Good meter for standard troubleshooting. Not recommended for precision calibration use. All functions work as needed. O-scope is limited in adjustment but it does work. I was able to use it to see the 20-70ms pulse width signals from a breaktor module on a EV battery disconnect. Everything else I have used it for has been basic and it works as needed. The battery holds up well so far. Did not like to use this meter at 1st but has become my go to meter as I get more familiar with its abilities. I would recommend this for advanced or advancing electrical users. Not ideal for beginners as you need an advanced understanding of electricity to understand the settings needed to get desired results. The unit has a nice auto feature to help with this but I find the auto readings are not always what I am after. The manual settings can get you dialed in. If you need advanced readings for troubleshooting then this meter will most likely get you what you need. If you don’t need the advanced readings then get a simple meter.

Meter has a high quality enclosure, and fit and finish are excellent. Has good weight for the hand and is comfortable holding for long periods. Using the various functions is very easy and intuitive. Color screen is beautiful. Especially the oscilloscope screen. Beep is loud, even for my old ears. The menu system really rocks on this meter. Very simple to navigate and easy to understand. Accuracy is on par with my more expensive Fluke meters and the kickstand is very sturdy for bench use. The buttons have a good feel when you press them. They don't feel cheap. Value is quite excellent for it's price range. When I wear this one out, I will want the same model as a replacement. Overall, high marks. Thank you Fnirsi for such a fine product in it's price range. I would definitely recommend this scope/dmm to those looking to buy their first one. Even as a replacement. I am totally impressed with this meter. If you are looking to buy one, go for it! You won't regret it. Very high quality.

I was quite impressed with this cute device. However, my excitement died down in 24 hours. First, the off-on button stops responding. My device is set as 15 min auto turn off and I'm using that to turn it off. The button works to turn the unit ON. The other feature I liked very much is I the save feature while using it as an oscilloscope for record keeping of output signal. It was working great for a few days, but now it stopped working. At this rate of failure, the unit would be out of life in a month. I am planning to return it. Very disappointed.

The resolution of the display screen is very low, the visual grain is very strong, and the screen is soft to the touch.Why can products be made of very comprehensive functions, but the display screen is made of poor materials?Another point, when you open the express delivery, you can see the outer packaging and think it is the wrong delivery(Chinese charactertics). All in Chinese, and a lot of Chinese in the manual book, I think it is unnecessary, which is very confusing to customers.The storage function of the oscilloscope is not powerful enough, and every time a file is named, 1.bmp, the 2.bmp etc can actually be named with a timestamp to make it more concise and easy to understand. Finally, the navigation settings of the software interface are not easy to operate. It takes a while to get used to it.Can not find rolling interface.

Major improvement over my antique Tektonix 465! Once I became familiar with the comprehensive manual's terminology & vocabulary, I was able to do some tests I was unable to do with my partially working Tek 465. I appreciate the full complement of 1x/10x scope probes, signal generator cable, and other supplies. Handy to save waveform & measurements screenshots to a USB-sharable "disk" for later printing with a computer.I am very satisfied with this purchase.
