A multimeter allows you to measure voltage, current or resistance. With a multimeter you can diagnose where a problem is in an electronic circuit or check to ensure that the component you are using is the value that you expect.
What is the advantage of a multimeter being autoranging?
The autoranging functionality on the multimeter will ensure that the multimeter is taking the measurement in the most suitable range. The range selected will alter the precision of the reading which is taken.
What are the advantages of an oscilloscope?
An oscilloscope allows you to take a reading and view it over a period of time. If you are measuring something which is changing it is very difficult to get an accurate reading using a traditional multimeter.
