Multi-meters Quiz

What measurements can multi-meters be used for?

• Temperature and pressure

• AC and DC voltage, AC and DC current, and resistance

• Speed and acceleration

• Humidity and altitude

What functions do multi-meters combine?

• Functions of a barometer, hygrometer, and anemometer

• Functions of a voltmeter, ammeter, and ohmmeter

• Functions of a thermometer, calorimeter, and spectrometer

• Functions of a GPS, altimeter, and compass

Besides voltage, current, and resistance, what other functions may multi-meters have?

• Time and frequency measurements

• Diode and continuity tests

• Mass and density measurements

• Light intensity and wavelength measurements

What is a digital multi-meter (DMM) commonly used for?

• Measuring the parameters within an electronic or electrical circuit

• Testing the durability of electronic devices

• Measuring the distance between two points on a circuit board

• Calculating the power consumption of a device

How many digits do most digital multi-meter displays have?

• Two

• Three

• Four

• Five

What is the indication for the first digit on a digital multi-meter display that can often only be either a 0 or 1?

• It indicates the power status of the DMM

• It shows the battery level of the DMM

• It is a +/- indication

• It represents the measurement mode (AC/DC)

How many main sockets for the leads are there on a digital multi-meter, even though only two are needed at any one time?

• One

• Two

• Three

• Four

What is the common/earth socket in a digital multi-meter used for?

• It is used for high current measurements.

• It is used with all measurements and takes the negative or black lead and probe.

• It is used for taking resistance readings only.

• It is used for the positive or red lead and probe.

Which connection on a digital multi-meter is used for most volts, ohms, and frequency measurements?

• High current

• Common/earth

• Amps and milliamps

• The positive or red lead and probe connection

What should be used for high current measurements in a digital multi-meter?

• The common/earth connection

• The battery

• A separate connection

• The same connection as for low current measurements
