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 bought this to set up my audio equipment in my car and so far I’m more than please with the results, after playing around with and seeing what I can do with it I’m hoping that I can inject a 40Hz signal and take a voltage reading at the same time I’m just not sure this meter will do just that but if it doesn’t I do have another voltmeter to get that measurement. We will see as time goes by and I play around with it to see what this thing will do. Of course I’ll give an update if after time it does more than expected or starts to disappoint. But either way I believe for what I know it can do at this point it’s well worth the money just having a handheld oscilloscope and voltmeter combined.

This is simply the greatest thing slice bread. This oscilloscope / multimeter has no equivalent in the below-$100 category. How do I know? I keep buying them, looking for an oscilloscope at $80 with $400 features. Well, this time it worked, mostly. The screen is perfect, the menus are intuitive, the ergonomics is well thought out. You can take it with you thanks to the long lasting battery. The multimeter returns correct values within 0.02 or 0.03 volt, or so. The oscilloscope give me the same curves as my expensive bench one below 50 MHz. The only weird stuff was the wave generator, which works perfectly, until you ask it to give you 1 Hz. It’s downright bizarre. The easiest square wave to generate is off… Too easy?!?

Item arrived ahead of schedule (took only 3 days with free shipping). Reasonably well translated manual, but unclear how to get into the global settings, took me about an hour to get the menus switched to English. Oscilloscope works well and has plenty of features for the price. Display is clear and bright, good quality probes included. Good value, just needs to be easier to switch to English. Only tested to 500KHz so far. Nice case

The best meter I've ever had, with built-in oscilloscope. Great battery life so far, the industrial design and screen user interface is very pretty, and it replaces two bulkier devices with just one that can do it all. Panel buttons & ergonomics are also top notch, I didn't have to read anything and could use it immediately.

Works ok for my needs. At first recharge the battery only lasted 30 minutes, turns out to be operator error. I charged it until the battery icon was full, but discovered after some research, that behind the little rubber cover over the USB charging port, there is a little LED that turns green when fully charged. Took several hrs to fully charge and have used for several hrs with the battery icon on the screen still showing full.Also note that the signal generator will remain on after being turned on, even if you switch to O-scope or multi-meter function, it must be turned off while in the signal generator screen with the play/pause button. OFF/ON for the signal generator is indicated in the upper left corner of the screen. It takes a little bit to learn how to navigate through all the functions, but well worth it. For the price, Im very happy with it.

Pro: It does what it promises, and for the price, it's not a bad unit. It comes with a nice carrying case and all the necessary probes. If you mostly want it as a voltmeter and just occasionally need to look at a waveform, it's probably a viable choice. If you already have a voltmeter though, buying this device makes less sense as the additional functionality is rather limited. Con: * The screen is too small, low resolution, and not bright enough, even at its brightest setting, to comfortably work with waveforms, and I wasn't even trying to use it anywhere near full daylight. Especially the grid is virtually impossible to see under any lighting conditions and there is no setting to make it brighter. * Having 8-bit resolution was standard for a long time, but economical scopes have come on the market a couple of years ago with 12-bit resolution at >= 1 GSa/s, leaving this device far behind in signal resolution. * Even more limiting is the miniscule 1k storage depth. With that limitation you can't really use the device for anything more than simple repeating waveforms. Trying to make sense of any digital data communications bus over any significant period of observation time will be next to impossible. * Limiting the signal generator to 50 kHz max is also a curious choice. With that, it's really not meant for anything more than checking out some audio equipment. * The BNC connectors on the device are closely spaced together and recessed to make them fit on the available space (top edge) and not stick out from the device. While this might look good, it makes it almost impossible to fiddle the probes' BNC counterpart onto the connectors, since you can't really grab and turn them, given the recessed position. Also, high quality probes that have thicker shielding at their base don't fit at all because of the recess. This is a major physical usability design flaw.

Great meter! I don't really use the oscilloscope, but the voltage and resistance works great. Took a little bit to get used to the settings. I would buy again!

This unit seems to gather some hate for not being like a full power oscilloscope. I say it is very cool for what it is, a voltmeter with oscilloscope functionality in a handheld. I have a full size Rigol dual channel scope I like a lot. The biggest difference is the full size has lots of knobs you can turn to smoothly change the timing, volt range and other features. But this is about the same price as a decent voltmeter, and I can certainly see taking this onsite to not just look at the voltage, but see what the line is doing and maybe do some advanced debug without hauling the big scope out.
