Example:
At a hypothetical installation the LEDs are Green-Orange with 3 green blinks (left
LED) and 6 orange blinks (right LED).
The number is 36 + 124 = 160
The next periodic maintenance reading has Orange-Orange LEDs with 8 orange blinks
(left LED) and 8 orange blinks (right LED).
The number is 88 + 62 = 150
The variance is 160-150 =
10 Units
The percentage of variance will be (10/160)*100 = 6.25% less then previous
alignment.
