The speedometer mounted on your car reliably measures your vehicle’s real-time speed. To illustrate the calibration of car electronic speedometers, we’ll take the VDO speedometer with LCD Display for an instance.

Nowadays, many speedometers are electronic, in designs derived from earlier eddy-current models.

In designs derived from earlier eddy-current models, a rotation sensor mounted in the transmission delivers a series of electronic pulses whose frequency corresponds to the (average) rotational speed of the driveshaft, and therefore the vehicle’s speed, assuming the wheels have full traction. The procedure is a relatively simple procedure, and can be accomplished in three ways- automatic calibration, manual calibration or the pulse-per-mile calibration and fine tuning.

These articles cover a wide variety of topics organized into 8 categories to facilitate people who are searching for these kinds of information or people who want to know more about their vehicles. While the conventional mechanical speedometers use gears and wires to determine speed, most modern vehicles use speed sensors in the electronic speedometers.

Besides, it recommends a selection of high performance diagnostic tools that have been approved and commended by many car owners.

As the part in question turns, the magnets or teeth pass beneath the sensor, each time producing a pulse in the sensor as they affect the strength of the magnetic field it is measuring. You gain access to these calibration functions by pressing the button on the front of the speedometer and holding it in while you turn on the ignition. Alternatively, in more recent designs, some manufactures rely on pulses coming from the ABS wheel sensors. When you see the method you wish to use, let go of the button and that function will be enabled. A computer converts the pulses to a speed and displays this speed on an electronically controlled, analog-style needle or a digital display.

It can be used successfully only either on a road with the distance of one mile actually designated by markers or on a dynamometer.
