Calibration of my new YR1035+ internal resistance tester (Yaorea) doesn’t seem to be possible. I don’t necessarily think that I would use that option, but I know it’s important for many people and users here included. That option and Factory Reset has simply been removed and replaced with “- - - -“ in the menu 
.
Do you know a hidden developer menu or another way to calibrate it?
I know it’s rarely a good idea to tinker with the factory calibration, though.
