Analog multimeter Digital multimeter. A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [1] is a measuring instrument that can measure multiple electrical properties. [2] [3] A typical multimeter can measure voltage, resistance, and current, [4] in which case can be used as a voltmeter, ohmmeter, and ammeter.
The test consists of calling a reverting calling telephone number (ringback number) or a vertical service code with a standard telephone. Upon answering the call, the exchange plays a unique signal tone as a signal for the installer to hangup the telephone. The exchange then places a reverting call to the originating line, causing the telephone ...
In a diesel, the sensor will control the fuel injection. The sensor output may also be related to other sensor data including the cam position to derive the current combustion cycle, this is very important for the starting of a four-stroke engine. Sometimes, the sensor may become burnt or worn out - or just die of old age at high mileage.

Sensor, hypernym for devices that measure with little interaction, typically used in technical applications. Spectroscope is an important tool used by physicists. SWR meter check the quality of the match between the antenna and the transmission line. Universal measuring machine measures geometric locations for inspecting tolerances.
This is a list of auto parts, which are manufactured components of automobiles.This list reflects both fossil-fueled cars (using internal combustion engines) and electric vehicles; the list is not exhaustive.
Pomona Electronics is a company specializing in electronic test equipment and accessories. It was founded in 1951 by Joseph J. and Carl W. Musarra, who were brothers. [7] [8] Founded to manufacture test cable harnesses for examining television cathode-ray tubes. [9] the company started in a factory location around the size of a living room. [9]
A chassis dynamometer.. A dynamometer or "dyno" is a device for simultaneously measuring the torque and rotational speed of an engine, motor or other rotating prime mover so that its instantaneous power may be calculated, and usually displayed by the dynamometer itself as kW or bhp.
