  1. Daily Sprint START • Is a non-metal a conductor, insulator, or semiconductor? • Is a metalloid a conductor, insulator, or semiconductor? • Draw a manganese atom (Atomic number: 25).

  2. Quick Review • What are some characteristics of metals? • How many valence electrons does a conductor have? • How many valence electrons does an insulator have? • What are some characteristics of non-metals?

  3. Using a MultimeterPart 1

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

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

  6. 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

  7. Where should you set the meter if you expect a reading around . . . 1000 volts 200 volts 20 volts 2000 millivolts 200 millivolts Manual vs. Auto Ranging 6 volts 50 millivolts 800 millivolts 800 volts 125 volts

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

  9. Hook Leads Alligator Clip Leads Test Leads Standard Test Leads

  10. Continuity The continuous flow 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?

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

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