MANAGE YOUR MEASUREMENT ERRORS
By Jordan Dimitrov, Centennial College

Test instruments such as oscilloscopes and DMMs
(digital multimeters) often let you get the measurement results you need with
just the press of a button. But the number on a meter's display or the waveform
on an oscilloscope's screen is not a perfect measurement. The value displayed
is never exactly the same as the value that was applied to the instrument's
input. In addition, instruments use different methods for making the same
measurement. Errors are always present, and you need to know how much error you
can tolerate.
