FNIRSI2C53T Upgraded Handheld Oscilloscope, 50MHz Bandwidth, 3IN1 Digital Oscilloscope Multimeter DDS Generator, 250MS/s Sampling Rate, 19999 Counts, Voltage, Current, Capacitor, Resistor, Diode Test

Really like it. So much easier that having to carry an o scope and multimeter around. The signal generator is an added bonus.Great machine just wish it had a PC interface other than just transferring images.

Nice test combo in this package. Compact and strong unit. Value of cost. Happy with purchase. Can't beat it.

Pros: Very functional and good value.Cons: Interface is a bit clunky and battery charge doesn't last too long.

I couldn't ask for a better two chanels scope.

The media could not be loaded. So far the scope seams to barely function. Adjustments to the horizontal often cause the device to restart.Use of the AUTO button often freezes the GUI and you must wait for the battery to die before being able to use the device again.The function generator has a lot of problems. changes to the frequency are not always applied until stopping and starting the finction generators repeatedly. Output frequency doesnt match what is entered.Use of the FFT function does produce a spectrum, but you can not enlarge it, apply markers, or get any reference points, which makes it useless. Thos should be a seperate display like the dmm and oscilloscope.In short, the firmware is not yet ready for market.Have reached out to the manufacturer through amazon and their website. Have yet to receive response.Frequency measurements are much more than 5% off for example setting the frequency to 5hz produces a 20hz signalFirmware v1.0.3Edit: the manufacturer contacted me and indirectly asked me to recalibrate the device. Their english is not very good so there is a language barrier. This has fixed a lot of the issues with the auto button freezing the device. And I believe it has reduced the number of times the device randomly restarts.Edit:After comparing reading to my fluke87 i started searching for their tolerance list,DC voltage +-(.05%+3)This is a funny way to say +-(3.05%) which is about what I saw.Not going to test the rest, sending it back today.Its good for the price, but after your first year of EE courses, you will have out grown this meter.They offered a full refund very quickly.

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.

Great pocket all in one oscilloscope/multi meter.

Perfecto y muy a tiempo llego justo en el momento que me anunciaron fue una excelente compra maravillosa muy recomendado
