An analog frequency meter, also known as an analog frequency counter or simply a frequency meter, is a type of measurement instrument used to determine the frequency of an alternating current (AC) signal. Frequency refers to the number of cycles or oscillations that occur in a unit of time and is usually measured in Hertz (Hz).
Tips: How Does Analog Frequency Meter Work?
An analog frequency meter, often known as an analog frequency counter, measures the frequency of an input signal by converting it into a proportional mechanical motion. It utilizes a resonant circuit or oscillator that generates a signal whose frequency matches the input. This generated signal is then used to drive a mechanical movement, typically a pointer on a circular scale. As the input frequency changes, the mechanical system resonates, causing the pointer to move along the scale. The position of the pointer indicates the frequency of the input signal. The scale is calibrated such that the pointer's position corresponds directly to the input frequency. Analog frequency meters are simple and intuitive but are less precise than digital counterparts. They work well for visualizing frequency trends and can be found in various applications like audio equipment and power systems.
