DPOX180H is what you see at the moment of recording, there is no data to the right or left.
A maximum of 25K points have gone down on the display.
The zoom function does not give better resolution.

I'm compiling a list of  key combinations not shown in the Menus or indicated above the keys (Some are documented in the manual, others are not). My idea is to print this on a card and put it inside the oscilloscope case as a cheat sheet. If you know of any combination I'm missing please let me know.

<MENU> : Has to be done inside this menu
((KEY)): Hold down for a couple of seconds

High Refresh Rate<Disp> ((Run|Stop))XY ModePower + OKCheck version<Set> ((V))Direct Trigger Level AdjPower + 🡄 / 🡆Zoom Mode((s))Overclock Mode<Aux> ((🡅))Normal Clock Mode<Aux> ((🡇))Freeze Wave As Reference((F1))Measurement Background Color<Set> ((s)) USB Connection Mode<Set> ((ns))Reset Osc. Settings<Set> ((Auto))Grid On/Off<Set> ((mV))TV Output<Set> ((Run|Stop))DC Offset Calibration<Meas> Press "CH1/CH2" then ((V))
            Use 🡅/🡇 to calibrate CH1. 🡄/🡆 for CH2.
            Must be done for every vertical scale.AC Gain Calibration<Meas> Press CH1/CH2 then ((mV))
            Use 🡅/🡇 to calibrate CH1. 🡄/🡆 for CH2.
Keep in mind that Zoom and Calibration modes are only available in firmware 1.2.8C+
ALSO, Changing the measurement background is a bit more annoying in that version of the firmware, because every time you keep "s" pressed, even inside a menu, the zoom mode will kick in. So you need to long-press "s" again to disable the zoom mode AND change the background color from inside the menu.

It would be great if Zeeweii would fix this, so once you are inside a menu long-pressing "s" doesn't toggle zoom mode.

EDIT:
I was casually looking into calibration-related posts in this thread, and discovered that Aldo22 had already made a great cheatsheet that is pretty much exactly what I had in mind  :clap:. I'm keeping my post because unlike the PDF I guess this post is "searchable" and will lead people to Aldo22's great work.

You just have to live with that or downgrade to the stock version v1.2.8C that I included in the zip file, and loose of course, the ability to manual calibrate the scope, and the zoom feature although buggy and incomplete it could be useful in same situations. Zeeweii won't fix that, they won't work on this firmware for the near future. They collect suggestions to release new products, just like most of the manufacturers of this low cost devices do.

Thanks, that reminded me to update the cheat sheet.

By the way, there is also a graphically designed cheat sheet by Old man 45.

timschuerewegen:
Thanks. I ordered one. I am probably going to hack/modify the firmware, to make it look nicer.

What you see in the lower part corresponds to the dark section above.
I hope it helps.
