A frequency meter is a device used to measure the frequency of a periodic electrical signal. It is represented as the number of cycles per second in an alternating current (AC) signal and is measured in Hertz (Hz). In its simplest form, the frequency meter is able to detect the number of cycles occurring within a fixed time interval.
A frequency meter is typically used to analyse the performance of different electronic circuits and devices. As such, the meter plays an important role in testing, troubleshooting, and monitoring electronic and electrical equipment.
The frequency meter symbol is a graphical representation denoting the presence of this device within an electrical system.
The appearance of this symbol may differ based on the manufacturer and meter type, but it is often portrayed as a circle with the Hertz (Hz) abbreviation inside of it.
