   In electrical engineering, characteristics like current or voltage can be measured by an ammeter, a voltmeter, a multimeter, etc.The ammeter is used in series with the load, so the same current flows through the load and the ammeter.

   Inexpensive analog meters may have only a single resistance scale, seriously restricting the range of precise measurements. Typically, an analog meter will have a panel adjustment to set the zero-ohms calibration of the meter, to compensate for the varying voltage of the meter battery, and the resistance of the meter's test leads.

   North American domestic analog (Ferraris disk) electricity meter. Electricity meter with transparent plastic case (Israel) An electricity meter, electric meter, electrical meter, energy meter, or kilowatt-hour meter is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device over a time interval.

   Probably the largest use of galvanometers was of the D'Arsonval/Weston type used in analog meters in electronic equipment. Since the 1980s, galvanometer-type analog meter movements have been displaced by analog-to-digital converters (ADCs) for many uses. A digital panel meter (DPM) contains an ADC and numeric display.

   In other cases, a third party might read, bill, and possibly even collect for the service. Some of these companies also install and maintain meters and reading systems. [citation needed] Panel or circuit submeters are used to measure resource use of the same system for added security, economic, reliability, and behavioral benefits.
