Definition

1. Noun:
   • An electronic voltmeter that gives readings in digits: A "digital voltmeter" is an electronic measuring instrument used to determine the electric potential difference (voltage) between two points in a circuit. Its key characteristic is that it displays the measured value as a numerical readout, typically on an LCD or LED screen, rather than using a moving pointer on an analog scale.

Usage Examples

• Noun:
  • The technician used a digital voltmeter to check the battery voltage.
  • For precise measurements, a digital voltmeter is preferred over an analog one.
  • The reading on the digital voltmeter indicated 12.6 volts.

Advanced Usage

• "Auto-ranging digital voltmeter": A type of digital voltmeter that automatically selects the correct measurement range, simplifying operation.

  • The auto-ranging digital voltmeter is ideal for beginners as it reduces the chance of incorrect settings.

• "High-impedance digital voltmeter": A voltmeter designed with very high input impedance, minimizing the current it draws from the circuit being tested, which prevents it from affecting the measurement.

  • Use a high-impedance digital voltmeter when measuring sensitive electronic circuits.

Variants and Related Words

• DVM (n): A common abbreviation for "digital voltmeter".

  • The DVM showed a stable reading.

• Multimeter (n): A more general electronic measuring instrument that typically combines the functions of a voltmeter, ammeter, and ohmmeter. Many modern multimeters are digital.

  • He set his digital multimeter to the DC voltage setting.

Synonyms

• Electronic voltmeter: A broader term for voltmeters that use electronic circuitry, which includes digital types.
• Digital multimeter (DMM): While a DMM measures more than just voltage, it is a common tool that performs the voltmeter function digitally.

Related Phrases

• To take a voltage reading with a digital voltmeter: The action of measuring voltage.

  • Always ensure proper polarity when taking a voltage reading with a digital voltmeter.

• Digital display/readout: The method by which a digital voltmeter presents information.

  • The digital readout was clear and easy to read under bright light.
