One of the qualities
of
measuring instruments is their sensitivity.
A measuring instrument is more sensitive the smaller the
quantity that it is able to measure.
The sensitivity with which measuring instruments are made depends on
what they will be used for. It makes no sense to produce some scales
which measure mg for a baker to use.
The sensitivity of a measuring instrument indicates how many figures of
a measurement are significant. Find out how many figures can be known
as a result of a measurement taken in the following visual.
