    Self-Test 1

    1. What are multimeters used to test, in addition to amperage and voltage?
      1. Pressure
      2. Humidity
      3. Resistance
      4. Temperature
    2. Analog meters are more popular than digital.
      1. True
      2. False
    3. How many volts are in 2200 mV?
      1. 0.22 V
      2. 2.2 V
      3. 22 V
      4. 220 V
    4. It is important to turn the circuit off before checking voltage.
      1. True
      2. False
    5. What would happen if you connected the probes backwards when checking voltage?
      1. Damage to the DDM would occur.
      2. Damage to the circuit would occur.
      3. A negative voltage would be read.
      4. It doesn’t matter which way they go.
    6. What is one important safety technique when testing electrical circuits?
      1. Wearing gloves
      2. Wearing safety glasses
      3. Using the one-hand technique
      4. Using the two-hand technique
    7. The first step when using an autorange DDM is to select the range required.
      1. True
      2. False
    8. A circuit must be broken to test current.
      1. True
      2. False
    9. Is an amperage test done in series or parallel?
      1. Series
      2. Parallel
    10. When is it important to turn off a DDM to extend battery life?
      1. After checking voltage
      2. After checking amperage
      3. After checking resistance
      4. Never; it turns off automatically

      1. Infinity test
      2. Overload test
      3. Continuity test
      4. This test cannot be done.
