One of the most common measurement errors is using the wrong tool for the job. For example, using a tape measure to estimate small mechanical tolerances or relying on a bathroom scale to track precise ...

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 ...
