Hello Tautech, thank you very much for the recovery kit, I put it on a USB and it ran, it seemed to work, but it stayed the same since it already worked and I already had the latest version of the software.
That is to say, it stayed the same as it was.

Recovering the old telnet thread on the SDG1032X, I was able to manually modify the file by Telnet and put my real serial number back into it.
But calibrate it I still don't know how to calibrate it...
My reference is the SDM3055 that I bought a week ago and it comes calibrated.
Well, putting the SDG1032X in:
C1: DC 1mV the SDM3055 measures 2.762mV and the UT-71E measures 2.7mV
C2: DC 1mV the SDM3055 measures 2.834mV and the UT-71E measures 2.8mV
