The average value of each AI can be reached on a regular interval when the moving

average function is enabled.

For example, a five-item simple moving average would be the sum of the reading

value of the five most recent reading value, divided by five; a 20-item moving average

would be the sum of the 20 most recent reading value divided by 20, and so on. Each

item the most recent reading value is added to the equation and the most distant item

is dropped off.
