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

This seems like a nice unit, but the oscilloscope is unusable without instructions. It did not come with any and I haven't found a downloadable user manual. Went from one star to five, found a very thorough user manual PDF and downloaded it.

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.

The user interface is obtuse as other reviews suggested. I don't use it all the time and I almost always have to go back to the manual to figure out how it works. Once I finally get it set up it works fine. Would be nice if the default settings could actually do something useful like specifying how long to stay on and default voltage and frequency settings.

Just invest in a nice one.

Inaccurate readings on measuring capacitance compared to label and verified with a Fluke 79 series II Quite satisfied with oscilloscope functions

The product was to complicated and overkill for the project I was doing.

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.
