What is another word for peak voltmeter?
Pronunciation: [pˈiːk vˈə͡ʊltmiːtə] (IPA) 
A peak voltmeter , also known as peak meter, is a device used to measure the highest voltage level of an alternating current (AC) waveform. Sometimes referred to as a crest meter, it is commonly used in audio systems to measure the peak level of a sound wave before distortion occurs. Synonyms for peak voltmeter include crest meter, peak level meter, peak measuring instrument, peak voltage meter, and waveform analyzer. Other related terms include peak-to-peak meter, which measures the difference between the highest and lowest points of an AC waveform, and RMS meter, which measures root mean square voltage which is related to the average power of the waveform.
