Nice product 👌

水晶振動子の動作確認用に使いましたが正確に発信周波数をとらえています。

Nice handheld scope. Had it for a few weeks and it seems very functional. Compared some traces with a 4 ch LeCrow and it was very comparable (digital CMOS logic gates). It's a small screen for sure, and the grid lines are a little hard to see even at the highest brightness. The function generator is a bit limited - seems to go up to 50kHz. Another cheap handheld scope I had (and lost) went to 1M. There a multimeter mode as well that looks functional. It plugs into a PC but I think it's to transfer over screen shots - I don't see any SW on their web site to control it remotely over USB. A good deal for sure. A nice case, some ok probes, and some misc cables to use with the DMM are included. I checked them and they all worked in my copy

It's a great product for all technicians.I had used this product before in another country its very nice and easy to use.

Recently purchased, good, complex device, need more time. Thanks 👍

I have used the FNIRSI 2C53T for about few months. It is a small unit with multimeter,function generator and oscilloscope. This makes work easy on a bench. The auto mode is helpful, but I often choose the function myself (volts, ohms, diode, etc.). The oscilloscope is good for my needs. 50 MHz is enough for hobby and school/college work. The menu felt new at first, but after a quick read of the guide and a couple short videos, it was easy to use. The Auto key finds a signal fast. I still like to set the trigger by hand and change time/volts per division, so I can see the wave clearly. The screen is bright indoors. USB-C charging is simple. Battery life is fine for a day of light tests. The probes are OK for the price. For quick checks and projects, this tool saves time and space. I am happy with it and plan to keep using it.
