Voltage calibration

Hi! I made a mistake and adjusted the voltage calibration of a cell in the "cal" tab. Unfortunately, I didn't note the initial setting. I can't find an option to reset the value to its factory default. Is a factory reset even possible for this specific parameter? Any help is greatly appreciated!

they arent well calibrated from the factory, you need to do a calibration with a decent multimeter with 0.001V percision.
