Using the v10 board and measuring the voltage of the 12v battery I am using to power a pi zero W through a UBEC 5v power supply. Can I please check my hardware settings
min =0
max = 0
scale=3.118
to get the scale I set it to zero then using a multi meter checked the voltage which was 12.41 the system gave a result of 3.98 so 12.41/3.98 = scale of 3.118
measuring the voltage with my meter this is the only way I can get the correct voltage reading of 12.41V
Is my method correct please?
