Multimeter Basics Quiz

When measuring the mains voltage, the multimeter should be set to:

• Resistance mode

• DC Voltage mode

• AC Voltage mode

• Diode mode

To measure the resistance of a resistor using a multimeter, the resistor must be:

• In parallel with the multimeter probes

• In series with the multimeter probes

• Removed from the circuit or measured in a circuit with no power

• Powered on in the circuit

What does it mean if a multimeter displays a reading of 0 ohms (or very close to 0) during a continuity test?

• The circuit is open

• The circuit is closed, indicating a continuous path

• The multimeter is not functioning properly

• The circuit has high resistance

When testing a diode with a multimeter set to diode mode, a good diode should show:

• Infinite resistance in both directions

• Low resistance in one direction and high resistance in the reverse direction

• Zero resistance in both directions

• High resistance in one direction and zero resistance in the reverse direction

What setting should a multimeter be on to test for current flow in a circuit?

• Voltage

• Resistance

• Amperage

• Continuity

How should the probes of a multimeter be connected to a circuit to measure current?

• In parallel with the component

• In series with the component

• Directly across the power source

• Not connected to the circuit

How should the probes of a multimeter be connected to a circuit to measure voltage?

• In parallel with the component

• In series with the component

• Directly across the power source

• Not connected to the circuit

What is the primary function of the 'Hold' button found on many multimeters?

• To lock the current screen display

• To increase measurement accuracy

• To switch between AC and DC modes

• To save battery life

What is the correct way to check for a short circuit using a multimeter?

• Set the multimeter to resistance mode and measure across the power supply terminals

• Set the multimeter to voltage mode and measure across the component

• Set the multimeter to continuity mode and check between the points of interest

• Set the multimeter to current mode and measure in series with the circuit

Which two multimeter settings could be used to determine if a fuse is blown?

• Voltage mode

• Resistance mode

• Continuity mode

• Current mode
