What is a Multimeter? Multimeter - An instrument for measuring the properties of an electrical circuit

Who Uses Multimeters? • Electrical Engineers • Electronics Engineers • Scientists • Technicians • Electricians • Chemists • Networking Engineers • Computer Engineers • Many Others. . .

Manual vs. Auto Ranging Manual The user is responsible for choosing a setting by anticipating the output. Always choose a setting higher than what you think the reading will be.

Manual vs. Auto Ranging Auto The meter adjusts based on the input to provide the most detailed reading. Auto ranging meters are generally a little more expensive.

Continuity The continuous flow of electrons through a component or an entire circuit. If the answer to the questions below is yes, then there is continuity. Is the material a conductor? Is there an uninterrupted path between the two points?

Testing for Continuity Method 1 There will be a speaker icon where resistance is measured. The meter will beep to indicate continuity.

Testing for Continuity Method 2 Turn the dial to a setting for Ohms. The meter will read zero to indicate continuity.
