ASM Quiz 3

What is a multi-meter used for?

• Checking for AC or DC voltages

• Measuring temperature

• Measuring air pressure

• Testing for water purity

What should be done before storing the multi-meter?

• Set it to off

• Remove the batteries

• Leave it on

• Increase the voltage range

How can you test for continuity using an analogue multi-meter?

• Set the measuring knob to ohm scale

• Set the measuring knob to resistance scale

• Set the measuring knob to volt scale

• Set the measuring knob to amp scale

What should you do if the needle on the multi-meter does not move during a continuity test?

• The wire is disconnected

• The battery is dead

• The meter is broken

• There is no continuity

How should you set the range when measuring resistance with a multi-meter?

• Set it randomly

• Estimate the resistance value and set the range accordingly

• Set it to the lowest range

• Always set it to the highest range

What precaution should be taken when measuring electrical voltage above 50 volts?

• Avoid touching the electrical leads

• Increase the voltage range

• Use bare hands

• Stand on a wet surface

How does a clamp-on ampere meter measure current in a circuit?

• Measures the resistance

• Measures the field induced by a current passing through the clamp

• Connects directly to the circuit

• Measures the voltage drop

What should you do before testing a capacitor?

• Increase the voltage

• Remove the capacitor

• Touch the terminals with bare hands

• Put on insulated gloves

How can you test a capacitor using a digital capacitance meter?

• Set the meter to a higher setting than the capacitor rating

• Set the meter to a lower setting than the capacitor rating

• Touch the terminals with bare hands

• Use the meter without gloves

What should be done before proceeding with any test on electrical components?

• Touch the components with bare hands

• Increase the power supply

• Wear sunglasses

• Verify that electrical supply is not interrupted
