JiaRen:
The Software version is 1.3.26, the hardware version is 0c-01. I'll update on the rest later.
JiaRen:
So these are the pictures you requested

Something is broken, it is now quite clear.
Please can you do all again but now only for CH2.
In my last isntructons but jump over step 2.

Before step 3 shut off CH1 and Open CH2.
Select  Trigger source  CH2.
Other things just as same as before and this piece of wire things now of course CH2.
If there are significant differences compared to the previous ones, show pictures of them.

BTW, it looks weird that even with your "wire in hand" test traces are all only positive related to GND. This is weird.
And image 1. After selfcal and BNC open 1V/div. This extremely "fat" trace show that something is really wrong.

Also in your all previous images I can not see any negative signals, all are in positive side.
In oscilloscope there is 3 voltage bands.  I, II and III. 100mV/div is in this band I. (Band I = 0.5mV - 100mV,   Band II = 102mV - 1V, Band III is 1.02V - 10V/div)
(this is why I ask different settings, all these use different V band)

Then please do also this.

Set just factory defaults.
Inputs = Nothing connected. Just empty BNC.
After then turn also CH2 on.
After then adjust CH2 to 500μV/div  and CH1 also for 500μV/div
Do not adjust vertical position, leave it just center as it is.

Show image.

Here is the pic, andd for some reason i got shocked by the ground terminal, pulled out my test pen and this isnt suppose to happen no?

Reset, both channel.


Ground, test pen


EDIT: Changed the power cable, fixed the ground but the wave is still the same. Even initially, none of this getting shocked thing is happening, dont know why it suddenly appeared. Or not I would have been shocked even when im using my PC.

First these safety things.
Your scope must be connected to mains using protective ground!!!!!!!!  (3 terminal connection)
If your power is connected right way, it is impossible that GND have any this kind of voltage level.

There must be L, N and PE (Protective Earth (PE) what is also internally connected to oscilloscope all GND, whole internal metal box is connected tp PE )(GND)))!
This is mandatory for safety. As also told in user manual.
Never use oscilloscope so that power is connected to 2 terminal socket.

Based to your all images now, looks like there is hardware failure in your scope.
I have some things that I would suspect and that I would check inside the oscilloscope, but all of them also require sufficient skills and measuring equipment to do them.

But before anything else.  Check the connection of the oscilloscope to the mains, that it is correct. PE must be connected, and its PE line must also be in order.
