  1. Ohmmeters pages 75-80

  2. V A x R

  3. How much resistance in a load if the amperage is: .5 amps

  4. How much resistance in a load if the amperage is: 3 amps

  5. How much resistance in a load if the amperage is: 250 amps

  6. How much resistance in a load if the amperage is: .004 amps

  7. Ohmmeters pages 75-80

  8. Ohmmeters are self powered

  9. Ohmmeters are used to test the resistance in components and they must be disconnected from any other power source.

  10. 200 2K 20K 200K 2M 20M Most common scales

  11. Manual Ranging

  12. Auto Ranging

  13. Out of range indication if the resistance is higher than the scale you are on. UL OUCH 3

  14. The Meter will round off the reading if you are on too high of a scale. This can make your readings somewhat inaccurate

  15. Circuit board assignment

  16. Ohmmeters pages 75-80

  17. Ohmmeters are used to: • Test continuity in switches

  18. Continuity Test • Will beep with approx. 30 ohms or less
