Unlike the main display screen that is averaged 10 times per second, the
middle voltage value is not averaged. Instead, that voltage is updated 1000
times per second giving you a true real time voltage display, exposing every
dip. When you move servos, this voltage will change dramatically!
After your flight, you can look at the minimum and maximum values to see
what changes occurred while you were flying.
Note: The Minimum Voltage warning detection looks at the averaged voltage
value, not the absolute minimum real time voltage.
