2C42 Digital Oscilloscope Multimeter USB Portable 2 Channels 40MHz 250MSa/s Multifunction Tester

My cousin recommended this over all the other models on Amazon. My cousin was professionally trained in electronics by Raytheon. After spending some time with this unit, he actually likes this better than his very expensive Fluke unit which costs thousands. He has now decided to buy one of these. My advantage is that I can learn through his examples and I am seeing I made the right choice. No, it is not the cheapest choice, but in it's price range it is the best. The more I apply myself, the better the unit looks to me. Paying a little more for an excellent product will return countless unanticipated benefits as time goes on.

This "do it all" meter is great! I have used it in all of its capacity as a multimeter, wave generator, and oscilloscope. I use this meter all the time to check and develop my electronic products. The only downside is the battery does not stay charged when not in use (loses a bar approximately every 45 - 60 days of nonuse). With that said, for the price of an oscilloscope, you can buy 4 of these meters or buy one meter and save lots of money.

I bought this because I got tired of bringing my multimeter home from work, and I decided why not an oscilloscope as well. The multimeter portion is a little slow at reading but is dead on accurate. The oscilloscope portion is very accurate, but it can be confusing going through the menu's and the screen is small with few presets, this is not a problem for someone experienced with a scope who ignores presets anyways but would probably confuse newer scope users. It is not a professional scope, it works and works well but if you want a professional one buy a professional one, hantek sells professional scopes, as does nearly every other scope maker. I bought this so I did not have to bring my autel scope and scanner home or my fluke multimeter to mess with my own vehicles or my friends vehicles, it is great for sidework and great for smaller projects for users who are patient, but if you want automotive shop or electrician tech efficiency you need to pony up for a higher end model from hantek or the other makers. So far I have checked ac ripple on an alternator and done injector and coil waveforms with attenuators. One big gripe is the lack of the 20:1 preset, as those are the attenuators sold by hantek, but they start at 10:1 and skip 20:1, not an issue for someone who can divide but again not a newbie friendly feature.

Everything works great with it. Very accurate in the description. Only reason why i gave it a few less stars is because there was a few things missing that it said it came with. The BNC Adapter and the ground spring was missing. The other part is it doesn't come with instructions on how to use it, just a user's guide.

Had to change to one star, Zero would be better. No help from manufacturer at all. Fair DMM! Has a learning curve fairly accurate. Scope can be clumsy to use. Capacitance mode is non existent for any value from pfd to mfd. Haven't found a decent contact to inquire as to if there is a known issue or a SW change to correct the problem. Will keep on searching!

I have 45 years of electronic experience and this little handheld scope is very nice for the money. Highly recommend. I just hope its performance lasts.

This scope is excellent. I am using it in the commercial HVAC field. I am able to see Bacnet/MSTP signals and RNET signals. The multimeter works well. I highly recommend this device.

Got this scope just two days ago. I quickly noticed that, in the 'roll' mode (the trace moving from right to left across the screen), big spikes appeared periodically, about once every few seconds. These 'spikes' reach the top of the screen and are about half division wide, so they are really rectangular pulses (see picture). This is when the input of the probe in GND!! Also, there is a significant amount of offset between the 0v reference marker (the mark on the left edge of the screen) and the actual zero-volt line. This offset is clearly visible in the included picture. After going through the built-in calibration function, this off-set appears to be lowered but, after a few minutes, it came right back. I have a $40 pocket size scope. The screen of this $40 scope has a more appealing look and much higher resolution. I can tolerate the low display resolution and the offset but not the spikes. This might be a defective unit.

Me gusta bastante, cumple su función como DMM y oscilo. Lo uso para car audio y me da lo que necesito.

This looked a good item however the one I was sent had the connector missing from the kit and it was refunded. They could not send out a replacement or the part which was missing however, it did look like a good item for the price.

Very happy with this unit. Works well.
