The adjustable reference quantity is varied until the difference is reduced to zero. The best way to account for these sources of error is to brainstorm with your peers about all the factors that could possibly affect your result.
b.) the relative error in the measured length of the field. Greatest Possible Error: Because no measurement is exact, measurements are always made to the "nearest something", whether it is stated or not. Random errors: These are errors for which the causes are unknown or indeterminate, but are usually small and follow the laws of chance. Re-zero the instrument if possible, or measure the displacement of the zero reading from the true zero and correct any measurements accordingly.
