I have this unit. It works perfectly fine for testing VFD signals that drive pumps and motors . Also works great for setting amplifier gains for car audio amps. It's a nice tool for a field service techs like myself. It eats batteries though.

One big plus is the electrical isolation when working on VFD drives and such. Not bad for under a hundie.

I have tried similar devices in the past but always resort back to my good old Fluke 99

Triggering on a digital o-scope is a problem. If the trigger circuit is analog based it then would need to re:phase the sample clock which is really impossible. Probably in this case it is a digitized and compared to digital level to become "triggered". That will always be somewhat noisy and the trace will wiggle at the trigger point.

It is ok for servicing and fixing and the price is realy good. A mate of me have that 80Mhz version.

I have tek TDS700 serie, i have Fluke Scopemeter 199c and i have this dmm scope and i love it for small and fast debug, i try on switching psu repair and work great, 700v input are nice to work on live side, menu and fonction are slow compare to Tek or Fluke but is work! I take with me on road call, i use somme time at home to check my small electronic projet, scopememeter are not too big but is smaller and lighter. I recommand for beginner because low cost and do nice job, i recommand for professionnel to use in light and fast debug, spaire instrument.

I've used those at work, too. We did switch over to a 190-series scopemeter recently, but they all work great!

Whenever you drop your meter or it gets stolen, you are very happy that you were smart enough to leave your expensive one home and took that cheap one instead.

Nice scope if you need to be isolated from mains ground and for in the field or at home. Price seems reasonable enough. The specified tolerances are probably over the entire temperature range. Maybe you can open it and show internals on a follow up?

The multimeter part of it looks good, but the scope part is really poor. If you pay 25% more you get the cheapest of the Owon HDS200 series, and that's a much better scope. Dual channel, and real BNC inputs, and a much better display. If you just need a multimeter and something only to see that the waveform is there, then you can probably do that even cheaper than this. If the spacing between the OSC and COM had been standard size, you could have used a banana-to-BNC adapter, and maybe it would have performed better at the higher frequencies. But 40MHz on regular banana testleads? meh...

These combo units can be useful for automotive diagnostics work (as you mentioned), but they are typically used more as a type of data logger.. running on a very long timebase. Would 40 MHz BW be useful for fixing cars? I am not aware of any need.. Cheers,

BTW, thanks of the review of the scope-meter. Pretty good basic accuracy on Volts and Ohms.

I noticed there was an AC scale under the “scope” settings and you were using the DC setting….???? I wonder what difference if any it would make on the displayed signal? Capacitively coupled??? AC vs DC on an O’Scope doesn’t make much sense to me…

dc in direct input, ac goes through a capacitor

Many years ago I made the mistake of purchasing a Velleman HPS10 scope not dissimilar to this in terms of form factor. By far the biggest limitation was that it was single channel with no external trigger. Had it at least had an external trigger, it would have had some purpose, one could compare signal timings. I kept wanting to like it, getting it out every now and then when I thought I had a use case for it, but no, I was always left disappointed. Although not to quite the same extent, there is a further limitation of all handheld scopes, and that is the UI. Messing about with buttons rather than knobs isn't great for workflow. FWIW, touchscreens IME also remain a bit of a disappointment, their responsiveness being slow, and often incorrect gesture interpretation means it's usually a substandard experience compared to knobs.

Remember... once again... you are using YOUR leads. (at least that's what you said)
