Understanding Multimeter Readings

What is the unit of measurement for voltage on a multimeter?

• Volts

• Ohms

• Amperes

• Watts

How do you set a multimeter to measure DC voltage?

• Set the multimeter to the AC voltage (V~) setting.

• Turn the multimeter off before measuring voltage.

• Use the resistance (Ω) setting on the multimeter.

• Set the multimeter to the DC voltage (V⎓) setting.

When measuring current, which setting should the multimeter be on?

• The multimeter should be on the 'resistance' (Ω) setting.

• The multimeter should be on the 'current' (A) setting.

• The multimeter should be on the 'voltage' (V) setting.

• The multimeter should be on the 'frequency' (Hz) setting.

What does a reading of 0.5A indicate when measuring current?

• 0.5A indicates a resistance of 0.5 ohms.

• 0.5A indicates a current of 0.5 amperes.

• 0.5A indicates a current of 5 amperes.

• 0.5A indicates a voltage of 0.5 volts.

How do you interpret a multimeter reading of 200 ohms?

• The resistance is 200 ohms.

• The resistance is infinite.

• The resistance is 2000 ohms.

• The resistance is 20 ohms.

What is the first step before measuring resistance with a multimeter?

• Turn off the power to the circuit.

• Inspect the circuit for damage

• Check the battery level

• Measure voltage instead

Which setting is used to measure AC voltage on a multimeter?

• DC voltage setting (V-) on the multimeter

• Resistance setting (Ω) on the multimeter

• AC voltage setting (V~) on the multimeter

• Continuity setting (diode symbol) on the multimeter

What does it mean if the multimeter shows 'OL' when measuring resistance?

• The circuit is open or the resistance is too high to measure.

• The battery is fully charged.

• The multimeter is broken.

• The resistance is at its maximum value.

How can you tell if a circuit is live when using a multimeter?

• You can tell if a circuit is live by checking the color of the wires.

• A circuit is live if it emits a sound when touched with a multimeter.

• You can tell if a circuit is live by measuring voltage with a multimeter; a voltage reading indicates the circuit is live.

• The circuit is live if the multimeter shows a resistance reading.

What is the purpose of the probes when using a multimeter?

• To store measurements for later analysis.

• To calibrate the multimeter before use.

• The purpose of the probes is to connect the multimeter to the circuit or component for measurement.

• To power the multimeter during use.
