You guys this this labscope could do useful work? Was thinking about a hantek 6022be but this seems better.

I run an Owon labscope and like it very much Owon SDS7102v on Amazon

I have had look the link you posted and went the Owon website downloaded the software no demo mode on it but it looks Okay on windows 10 much nicer than Hantek but no automotive pre-sets

I could definitely use those automotive presents, being my first oscilloscope and all. I downloaded the hantek 6022be software and it doesnt seem to have any presets either. Really not sure which one i should get. I suppose the owon would be a bit better based on spec sheet

Working without pre-sets is something you quickly get used to it is very like tunning in an old style radio --- just twiddle the knob.
With Time base (X) and Voltage (Y) scales start with a higher voltage and slower time base than you need and adjust down untill you see detail .
To start out the Trigger should be set to "Auto" -- which really means the trigger is off and the scope will continually sweep across the screen without needing trigger.

The order to work in is (1) Voltage (2) Time (3) Trigger

(1) So for most automotive work a 20v scale is a good starting point -- then adjust the voltage scale down until you get the waveform at a nice size. At this stage you may not see any detail in the waveform just concentrate in getting the voltage a nice size on screen
(2) Time base (Seconds/div or Screen Size in Seconds) is how fast the trace sweeps the screen -- again start with a slow setting for example a 5 second screen which is suitable to capture a cranking compression test and adjust the seconds/division down until you see detail
(3) Trigger Think of the trigger as a trip wire that starts the oscilloscope sweeping the screen set the trigger level to about halfway up the waveform voltgeand then set the trigger to "Normal" --- this should give a nice stable image that refreshes every time the trigger is tripped.

There is more for example using the Trigger Level and Trigger type setting to "Single" to capture misfires and using the AC setting and Filters but that should be enough to getting things rolling. It is a bit like getting a new cell phone after a day or so you get used to it.

Hi. I have owned a pico for a few months and have been scoping anything I can get my hands on, just to learn more about it and get use to the characteristics of certain waveform compared to what is seen on forums and youtube.

Since using it I have never used the presets in the pico software, although this was one of my reason for buying a pico.
So if you are looking for a scope and are concerned about the presets I am sure once you have used it a few times, and got the hang of setting it up you wont even use the presets.
The pico also has a scale and offset function which brings the image to a comfortable size, so for instance if you capture a waveform and your voltage range was too high, the image will look smaller than you want. You can adjust your scale, zoom in, and the image will for your screen nicely.

Just to share my experience as a novice scope user.
