You know when you try a new supplier because the products appear good.. well I purchased a fee and really impressed- simple charging, easy operation and great bright screens…
FNIRSI® 2C53T Upgrade Handheld 3in1 Oscilloscope Multimeter Signal Generator
Good product for the price
Arrived on time. Well packaged. Easy to use. I had a small problem. When the battery was low, I put it on charge but couldn't turn it on after that. I couldn't find any troubleshooting in the instructions. Finally, I noticed a small hole to the right of the connector through which I was able to click the reset button. After that, it works properly.
UPDATE: Good news, the clamp test is compatible with 21700, but it's not immediately obvious, so I took some additional photos.
Turns out the lower tip is mounted on a fairly strong spring, and you just need to apply a bit of pressure to insert the 21700 format.
The clamp is amazing; I even managed to test the tiny 10180 format with it!
This multimeter is remarkable for its price and precision, especially when compared to a professional Fluke tool. While it falls short in terms of voltage measurement stability, it is highly precise when measuring internal resistance.
However, it’s not a full 5/5 rating due to the poor design of the new tester clamp. For instance, it doesn’t support the popular 21700 battery format, which is quite disappointing for a tool specifically designed for battery testing.
It’s unfortunate because just a few extra centimeters in the clamp design would allow it to accommodate 44 standard battery formats—something the SkyRC MC3000 charger achieves effortlessly.
To be fair, it is possible to insert a 21700 battery by removing the two adjustable screws at the back, which extends the tester clamp beyond its original limit (as shown in the photo). However, doing so applies unintended stress to the solder joints, which is not ideal.
On the other hand, the other tester probe is excellent, featuring spring-loaded tips that make measurements very comfortable. The only downside is its short cable, which prevents the probes from being positioned face-to-face horizontally, limiting usability in certain scenarios.
Indispensabile per conoscere le condizioni di una batteria. Economico e di buona qualità!
Fast checkout and quick shipping, just I didn’t notice there is no probe in this item package.
Its a nice, handy, mobile 2channel Oscilloscope with internal accu and very compact, its good to have a nice multimeter on board and signal generator, very useful when working outdoor on cars or machines in the field.
The signal generator does not have a standard connector, small MCX is flimsy. Has some issues with triggering signals and not really 50MHz, practically not much above 40MHz. Temperature sensor ist pretty much useless without external connector (sensor is inside case). Internal Fuses are _soldered_ to the PCB, thats a no go. Takes more then 600mA, so its good only for a few hours without charging. Cannot be fast charged with USB-C PD.
Input Jacks spacing is non standard, too.
ADC is overclocked.
But price is somehow good (if you manage to take all the available discounts) and for most work its a pretty useful device. Needs some love and some upgrades to make it really perfect. Could not find how to update software, where are the files?
This is my first programmable power supply and I really like the overall build quality and the compact form factor. So far it works great.

The product met expectations, the delivery was also fine. In short, everything was fine.
Easy to use, uncomplicated, great quality 😀
Nice product, I really recommend this brand thanks, gsystemlab 👍🏻
Maybe the first time but not the last!
Showcases some of the items I purchased to a colleague who was amazed at the quality of the build and impressed by the affordable price.
Is working fine. The only thing is to know what a charger you need! With the right one you will have a lot of fun and he successfully in your soldering process.
I test the multimeter to measure different elements and the results was very good.
FNIRSI 2C53P is a very nice product which incorporates a lot of functionality. The user interface (HMI) is nicely and efficiently selected by a touch control on the LCD. Room for improvement might be seen with the user manual. Many of the user interface can be handled intuitively but in my point of view even not everything. E. g. selecting different time base on the oscilloscope took a while to explore.
Works very good and produced in high quality. Nice carrying bag.

Small, light, well designed. It's a good product for the affordable price. It would be better if the screen is bigger. Thanks you
Product is very good!
