| 释义 | voltmeter noun[ C ] electronics specializeduk /ˈvəʊltˌmiː.tər/ us /ˈvoʊltˌmiː.t̬ɚ/ any of various devices used for measuring the voltage between two points on an electric circuit伏特计;电压表 Measuring, weighing, & counting devices -scopic adding machine detector dial dipstick dosimeter fitness tracker gage gamma counter gauge gradation indicator manometer micrometer probe scope smart meter straight edge theodolite tracker voltmeter | American Dictionaryvoltmeter noun[ C ] us/ˈvoʊltˌmit̬·ər/ physics a device that measures differences in electric potential between two points Examples of voltmetervoltmeter The shedding frequency was measured with an electronic counter, and an integrating digital voltmeter was used to obtain the pressure transducer voltage. The d. c. output is read on a high-impedance voltmeter. This error depends upon the resistance of the voltmeter. The e. m. f. was recorded by a digital voltmeter reading to 0.5 % or a potentiometer reading to a much higher degree of precision. A conductivity gauge, double-electrode conductivity probes, a digital voltmeter, and a chart recorder were used for the conductivity measurements. The voltage output from the wave gauge was fed to the averaging digital voltmeter to obtain the local mean water elevation. For this industry there must be a steady supply of electricity, because there must not be the most minute variation in the operation of the needle of the voltmeter.
