An analog meter is a type of meter used to measure various electrical quantities such as voltage, current, resistance, etc. It is usually equipped with a dial indicator and a scale, which helps the user to see the measured value accurately. The main feature of an analog meter is that its indicator operates within a specific range, and the size is shown by different numbers or marks on the scale. In these meters, changes in electrical signals are directly reflected by changes in the position of the indicator, which can be easily read by the eye.
Analog meters are generally simple, inexpensive, and reliable, and are still used in many applications today, especially where a continuity of observation or change is required. However, in the modern era, analog meters are being used less and less in many applications due to the increasing dominance of digital meters. Nevertheless, analog meters are popular in various educational and certain technical fields due to their simplicity and visibility.
