Automotive voltmeter: designation, description

Surely every man in his lifefaced with such a device as a voltmeter, and knows what is its main function. This is the determination of the voltage value of an electrical circuit. An analog voltmeter is a device with a pointer and scale. Recently, digital voltmeters have gained special popularity, they are characterized by more accurate readings and compact dimensions. In this article we will talk about a special model of the measuring device, such as automotive

st voltmeter.It can be performed as a simple voltmeter and a combined one. Combined automotive voltmeter contains additional functions, such as a tachometer, thermometer, etc. Let us consider in more detail such a device.

Automotive voltmeter has smalloverall dimensions thanks to what it can be established to any place of the car. Quite often, such a device is combined with a cigarette lighter plug. If necessary, you can insert the device into the cigarette lighter and use it to track the battery charge in various operating modes. Thus, the normal voltage of the battery with the "plugged" engine is 12.5 volts, and when it is running - 13.5-14.5 volts. If the voltage exceeds, or, conversely, below the norm, then you need to check the electrical system of the car. Automotive voltmeter is simply indispensable for those who like to listen to music, especially at a picnic or nature. It allows you to track the battery charge and prevent discharge below normal. Many motorists know that focus on the signals of regular automotive signaling

Battery discharge ores are undesirable since theyas a rule, they signal when a battery, generator or relay generator fails, and it is already too late to take any measures. Automotive digital voltmeter allows you to notice changes in the electrical system of the machine. There are options for connecting remote displays, so the driver will always see the instrument readings.

Now consider the combined devices.Automobile tachometer-voltmeter can be installed anywhere in the car, and, if necessary, under the hood. This device allows you to display not only the voltage on-board network

but also the temperature of the air inside the car andon the street, as well as the temperature of the car engine, and, of course, the number of revolutions of the engine. Such devices can be used not only in cars, but also at home to indicate the temperature inside and outside the house. Complete with a car tachometer-voltmeter, temperature sensors are sold. In the thermometer mode, the sensors are capable of measuring the temperature in a predetermined range from -50 to +127 degrees Celsius. Connection of the specified sensor can be carried out independently, and it is possible to entrust auto electrics.

Here we briefly reviewed what constitutes a car voltmeter and a combined instrument. Knowledge of how to use these devices will be useful to every car owner.
