Measuring Instruments True or False

A volt-ohm-milliammeter (VOM) can measure voltage, resistance, and current.

• True

• False

A reading of 3000 RPM on a tachometer means the object is rotating 3000 times per second.

• True

• False

An oscilloscope can display the wave form of electrical signals.

• True

• False

If a voltmeter reads 12.5V, it means the resistance in the circuit is 12.5 ohms.

• True

• False

An ammeter measures the electric current in a circuit in amperes.

• True

• False

A sinewave on an oscilloscope with a peak voltage of 5 Vindicates the highest point of the wave form is at 5 volts.

• True

• False

A tachometer is used to measure electrical resistance.

• True

• False

A reading of 200 ohms on a VOM indicates the circuit has a resistance of 200 ohms.

• True

• False

A volt-ohm-milliammeter is also known as a multimeter.

• True

• False

A frequency reading of 1 kHz on an oscilloscope means the signal completes one cycle every 1 second.

• True

• False
