Dear all,
Excuse me if my question has been posted by someone and if so, pls let me know.
I am having a situation to better define and explain to someone the difference between resolution and sensitivity. I can explain quite well that the resolution is the smallest scale of an instrument, for e.g. 1 mm in a normal measuring tape. But what is sensitivity??

Resolution is the smallest unit of measurement that can be indicated by an instrument.

Sensitivity is the smallest amount of difference in quantity that will change an instrument's reading.

A measuring tape for example will have a resolution, but not sensitivity. An analytical balance will have both issues. An ocilloscope will have sensitivity but may not have resolution issues, depending on several variables.

Hope this helps.
