Budget scope with long term recording?

to spend a few grand on a 'proper' scope I'm wondering if any of these budget scopes have a good recorder scope option?
For example - when I'm tracing a current draw on a vehicle I measure the voltage drop across a piece of wire in series with theĀ
battery over several hours, so I can watch as things turn off and the current drain falls away on some of these fancy European cars.
Sometimes I want to zoom in to an area of the screen especially when I have measured over 3-4 hours.
I had one of the Hantek 8 channel budget versions but couldn't even find out where to turn on voltage reading, let alone record
for extended periods.
is there a cheaper scope out there that is easy enough to use that can do this?

Ā This link takes you to a video on how to make the 2204 work with theāāāāpico 6 software.
He'sĀ got a website too where to contact him.

I might have to give it another try!

Note every different scope(same model numbers don't need extra license) you plug in will need its own license but the automotive will go with all scopes with a basic license.
I stole my scope off ebay with no probes for $32.
Now I do have another one I use to test secondary ignition as the Hantek doesn't like it. That one is a portable FNIRSI 1013D I believe I paid about $125. No whare neer the fearures of the Hscope but it holds its own at my place and because the screen is less sensitive the the tablet, I won't change something on it while under a dash.
Well actually I lied to you, I have a Modified Rigol 1054z running at 100mhz, a early 1950 Tektronix that I use to heat the room up with in the winter, it has 113 Vacuum tubes and is hot as hell. I have a heathkit tube unit that I'm recapping. And one other that I still can't figure out whats wrong with it but no real value.

In hscope go into settings, then click probes. In here you can download from the cloud a bunch of preconfigured probes or custom configure here. Just have a look, No problem if you want to use a in cyl press transducer, its probably already there or make one yourself. The hantek secondary probes are x10000. Not many cheap scope will let you configure that, I know my other ones won't.
Zoom feature, WOW, spread or pinch your fingers and it will zoom in a very very very long way. Same thing with time base. You can vary the rate of capturer from 50ns to 2 seconds per div. When you get the license it will enable longer timebase. Without the license its useless software.
He has a very strong following in the automotive module and he adds new stuff all the time. I used it to show someone a few months back that they had a bad cyl. and it took all of about 10 min. When you have a picture of the failure, its hard to dispute it.

a 2 or 3 hour recording while monitoring the voltage drop across a 'shunt wire' which equates to current draw.

Do you mind me asking what you're trying to chase down?

and put a long piece of wire in series with the terminal to create a slight voltage drop. This gives me a reference voltage to measure current at
and monitor current drain as it falls away, or returns. There's a sample on my blogĀ www.springbokphotography.com/autoelectri...nosing-battery-drain
Sometimes it's good to be able to leave a vehicle and go to another one for a while but still have a record of what the other vehicle is doing.

I had a quick play with it at work but I think this weekend I will have to play around a bit with it
to get the hang of it.

Don't get frustrated if it gives you problems, the settings to a bit to get used to. One thing I don't like about the Hantek(not Hscope) is, if it gets hit with enough signal it will reboot and set the probes back to x1 This is for sure in the hardware as it does it on openhantek as well.(linux software I believe that they have a working windows version but you have to do something with a driver and I'm linux user so I didn't go any further with it). I haven't tried it but I bet you could just download linux on a disk/memory drive and run it without any install then run open hantek. Nothing to install if you're a window person.
The factory software is terrible at best but it does work. OpenHantek is the best pc based software. Hscope is hands down the best software. There are people at sigrok that are working on stuff and the do have software but I couldn't get it to work. There is one more but I can't remember the name and it is windows based. Looks like a good start then never finished it.
