How to Calculate and Solve for Error | System Performance Characteristics
Last Updated on January 5, 2021
The image above represents error.
To compute for error, two essential parameters are needed and these parameters are Indicated Value and True Value.
The formula for calculating error:
E = I.V – T.V
Where:
E = Error
I.V = Indicated Value
T.V = True Value
Let’s solve an example;
Find the error when the indicated value is 22 and the true value is 10.
This implies that;
I.V = Indicated Value = 22
T.V = True Value = 10
E = I.V – T.V
E = 22 – 10
E = 12
Therefore, the error is 12.
Calculating for Indicated Value when the Error and the True Value is Given.
I.V = E + T.V
Where;
I.V = Indicated Value
E = Error
T.V = True Value
Let’s solve an example;
Find the indicated value where the error is 32 and the true value is 15.
This implies that;
E = Error = 32
T.V = True Value = 15
I.V = E + T.V
I.V = 32 + 15
I.V = 47
Therefore, the indicated value is 47.
Calculating for True Value when the Error and the Indicated Value is Given.
T.V = E – I.V
Where;
T.V = True Value
E = Error
I.V = Indicated Value
Let’s solve an example;
Find the true value when the error is 40 and the indicated value is 28.
This implies that;
E = Error = 40
I.V = Indicated Value = 28
T.V = E – I.V
T.V = 40 – 28
T.V = 12
Therefore, the true value is 12.
