New 2ch pocket DSO+SG - Zeeweii DSO2512G

Added some text in the <calibration> section of the firmware post

Aldo22:
I will probably upgrade. No risk, no fun.  :scared:

There's just something I don't quite understand yet:
After the DSO will be upgraded and restarts (with God's help), do I then have to calibrate manually directly as a step in the upgrade procedure, or can I start the device normally and calibrate/adjust later?

I ask among other things because I would then warm up the FY3224S for 15 minutes before upgrading, as you suggested.

Thank you.

after the scope restarts it enters the manual calibration automatically. read the log.txt file to find out about the keys to operate on this mode. If after it you don't like the results you can later enter this hidden function and do manual calibration of the measurements as many times you wish.

The 15 min wait time for the FG, is to allow it to stabilize in a proper working condition so that the output sinal become the most stable as possible.

You can also use your multimeter connected at the same time to compare with the values displayed on the scope, specially when doing DC calibration vs Mean value on the scope.

OK, the upgrade worked smoothly.
So far so good. It is not bricked.  :-+

A little irritating is that it is set to Chinese after the upgrade.
I was a bit helpless at the "Gain Calib" screen after power on. But after pressing OK you are in normal mode and you can switch the language.

I will experiment with the manual adjustment later.
After an "auto calib" it is already usable again.

Thanks for the FW and for the support!  :clap:

I'm glad everything went smoothly my friend. You can easily calibrate de measurements latter, is a little tricky to enter into that mode, but i think you can do it without much problems.
Enjoy your "new" scope!
