Analog and Digital Meters

The indication of electrical parameters such as AC voltage, DC voltage, AC current, DC current and frequency is an important task of electronic measurements. There are two modes of indication; (1) analog and (2) digital. Analog meters are used for analog indication and digital meters are used for digital indication. An analog meter is a device that features a printed display to indicate any electrical parameter. An example could be the energy consumed by a typical business, or electrical device. Also called an electromechanical meter, it offers an easy-to-read display. Digital meters are the product of the latest developments in electronic technology, so it is to be expected that they will incorporate many features that are not available in typical moving-coil meters. As well as a wide selection of voltage, current and resistance ranges (including accurate low-resistance range) many of these meters also provide for measurements of capacitance and frequency. This book describes both analog and digital meters.
