Calculations

Error =

((Primary Out AF or AL - Expected Primary Output AF or AL) /(Primary Output URV - Primary Output LRV)) * 100

For example, consider the following values:

• Primary Output LRV = 10
• Primary Output URV = 110
• Primary Output = 61
• Expected Primary Output = 60

Given these values:

Error = ((61-60)/(110-10))*100

Error = 1 %

RMS Error = √((Sum of the squares of individual error values for each test point)/number of test points)

For example, consider the following error values:

Test Point Number	Error Value (%)
1	2
2	2.1
3	1.95

Given these values:

RMS Error = √((22 + 2.12 + 1.952)/3)

RMS Error = 1.992
