Hi @JColvin,
Thank you for your reply and moving question's section.
I'll take a look at the thread you gave me and other threads.
Thanks,

Hello,
Because of my carelessness, I broke Scope 1 by 100V overvoltage.(Scope 2 is alive.)
Can I fix it by replacing the ADG612, which is the "Scope Input Divider and Gain Selection IC"?
Thanks,

Hi @attila,
Thank you for sharing the thread.
I'm surprised to see the exact same case.
I checked VREF and VOFF,
- VREF1 and 2 were both 2.0V
- VOFF1 and 2 were:
when 0V offset, both 2V
when +2V offset with 500mV/div range, both 3V
when -2V offset with 500mV/div range, both 1V
(To be exact, when -2.5V offset, "Channel 1 range will be extended" was displayed, so I set it to -2V.)
Secondly, I did "Load factory" and checked calibration is not changed.
I'm going to buy and replace ADG612.
I'll contact you afterwards.
Thanks,
