digital voltmeter

A technician uses a digital voltmeter to check a battery's voltage.

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.
