• rectifier

A meter used to measure resistance in ohms.

• voltmeter

• ohmmeter

• ammeter

• rectifier

An instrument used to measure voltage.

• voltmeter

• ohmmeter

• ammeter

• rectifier

A meter with a continuously variable scale. An indicating needle reads the measured value.

• shunt

• iron van meter

• digital multimeter

• analog meter

A meter that uses modern electronic circuitry to take electrical measurements and display values, usually on a liquid crystal display.

• shunt

• iron van meter

• digital multimeter

• analog meter

A meter created based on principles of repulsion. Two concentric vanes are placed inside a solenoid.

• field-effect transistor-VOM

• iron van meter

• digital multimeter

• analog meter

A device used to measure AC and DC voltage, AC and DC current, resistance, and describe ratings.

• field-effect transistor-VOM

• iron van meter

• digital multimeter

• analog meter

A meter scale with evenly spaced marking used to interpret ampere and voltage values.

• linear meter scale

• nonlinear scale

• shunt

• ammeter

A scale, such as the ohms scale, whose markings are not evenly spaced.

• linear meter scale

• nonlinear scale

• shunt

• ammeter

A unit of measurement of meter sensitivity.

• rectifier

• resolution

• volt-ohm-milliammeter (VOM)

• ohms-per-volt
