Should Handheld multimeters have color LCD displays?

There is no denying I got a warm fuzzy feeling when I powered on the scopemeter for the first time! But who doesn’t like getting new shinny things, or better yet, new test gear!
Ohh Scottie what frequencies does your induction cooktop switch at?
Let me make a loop antenna with my scope probe and measure it with my OWON HDS242 scopemeter:

Between 19 kHz and 36 kHz. LOL

I definitely love having a bright color display! Will I love the battery life that is the question!!

I was wondering what looked weird in that photo (apart from seeing the waveform on a multimeter!), and then realized that it just looks strange not having any normal multimeter test leads connected to it : ) 

It's a very much useful device than I originally thought.. I didn't realize it was dual channel.

I saw it too.

I think it's a lovely device. The first time I see a non-bench oscilloscope, and I think it's not a gimmick.

My bench space is limited. When I need a scope, I have to get it and give it bench space.
The Owon would be an excellent contender in a generic probing exercises.

For the price it was too tempting to not buy it and try it out. For basic troubleshooting/investigations/ basic sanity measurements I think it is a total winner (assuming I don’t blowout the frontend in the near future lol)

 Action Shots:

Probing 12 Mbit USB on a RPi Pico:

You can even see the 1 ms USB SOF packet

Probing the 62.5 MHz flash clock line is really pushing the scope to its limits. But you can clearly see the clock signal is there and alive!

(Why didn't the screenshot include the cursor delta 16 ns, not sure...)

scottiebabe , have you been able to talk (scpi) with the oscilloscope? It's not coming up as a test device, has no USB serial interface and LabVIEW doesn't know how to connect to it.

I have a manual for the instructions, but could not locate a connection manual. My google-fu hasn't gotten me further yet.

Someone on the eevblog posted a sample python script using pyusb, that is what I have been using. All credit to the forum author not me!

Using pyusb is surprising simple! I presume labview might let you do the same thing quite easily too

Great! it has the 0x03 and 0x81 bulk out and in handles. I think I can start from that

I believe it is 0x01 and 0x81

My scopemeter has the same vid/pid as my f-gen (which I believe is the same vid/pid as yours) so in pyusb I had to add one more search parameter to ensure I was talking to the right thing! 

dev = usb.core.find(idVendor=0x5345, idProduct=0x1234,product='oscilloscope')

I have it working in the NI VISA resource testbed:

.

.... and from  a LabVIEW test flow:

Yay!

This is awesome! Great work, I would much rather use the ni-visa interface over python... I will have to look into this! I didn't know you could do raw usb over visa

Thanks for sharing

Hi Jan

how did you get ni-Max to find it?

I don't recall it. Let me try to see if I had set up an alias, or if it found it automatically. Hang on ...

I  created a driver with NI-VISA Driver Wizard, then looked up what the right URI format is, for raw USB.

And based on the info in the wizard, and those instructions, I forged the URI:

Unfortunately, when I test it now, it doesn't connect. I hope I documented my work ...

I found my instructions back: community.element14.com/.../first-impressions-software-control-of-multicomp-pro-handheld-oscilloscope---scpi

It doesn't work anymore, though. Even though the device enumerates correctly, using NI-VISA's driver, I get no connection. 

No clue ...

Hi Jan

Thanks for reply, I know it is an older thread..

I can make the driver with the NI driver tool but, it wont accept the certificate.

I think it is some policy on Microsoft part that is more limited now.

The example from the thread based on Python is working fine, but i have a vba macro that i use with other instruments, and would like to add the OWON HDS242S to the bunch.
