Measurement techniques (1):

There are many electronics/electrical practitioners who have implicit faith in their measuring instruments and believe anything displayed on the these, particularly if the display is digital. There is more to measuring electrical quantities, however, such as knowledge of the instrument being used and the purpose of the measurement. With those in mind, it is possible to select the most suitable instrument for a given measurement. Judging and interpreting the measurements are the next important steps. Basically, each and every measuring instrument produces errors. The magnitude of such errors and how to arrive at meaningful results is the object of this new series of articles.
