Re: [RE-wrenches] small handheld oscilloscopes

Jay,
I just bought a Kmoon KKM828 for $80.55 on Amazon.  Got it in 12 days.
Works fine.  The last one I bought a few years ago was $170 and I lost it
and the one before that was $380 and it died from getting wet.  This is a
good multimeter with big colorful numbers when trying to read voltages in
dark places and has a sharper screen showing the waveform than the last one
I had.

Having never taken any formal training on using oscilloscopes, but knowing
that it might be useful to use one for diagnostics, does anyone have a good
resource for explaining how to use one for diagnostics of
inverters/generators/grid outputs?

[RE-wrenches] small handheld oscilloscopes

2021-01-24 Thread jay 
HI All,

Someone just told me about some small inexpensive Oscope.

I’m wondering if anyone has any recommendations.
I’ve been wanting one, and given the inexpensive price it might be a good 
option for simple waveform and diagnostics on problematic generators and 
inverters.

Here is one for example.

thanks
