A digital multimeter (DMM) is one of the most useful test instruments in any automotive electrician's tool kit. Every DMM is slightly different but there are some general guidelines you can follow for its use. An old analog voltmeter will work too but be careful of polarity when using one ...
How to Read a Voltmeter? Most vehicles nowadays contain a 12-volt electrical system. Therefore, when a car battery is fully charged and functional, it must read 12.5 volts when the engine is not running. On the other hand, if the engine is running, its alternator will recharge the battery...
For example, an analogvoltmeterwith a ±3% accuracy is set to the 0 to 100-V range. Based on this accuracy, its pointer can be 3 volts (100 V x 0.03 = 3 V) below or above the true reading. If the true measured value is, for example, 90.0 V, the meter might read between 87 ...

A multimeter is used to take measurements of electrical properties for a circuit such as the voltage, current, or resistance. A modern multimeter combines the abilities of legacy voltmeters, ohmmeters, and ammeters. Some of the uses of a multimeter inclu
How to measure voltage with a tester - choose the voltage (unit "V") parameter, then insert the test leads (black and red). Connect to a circuit and read the value.
An analog voltmeter works by measuring the current through a fixed resistor. Now, according to Ohm’s law, the current through the resistor is directly proportional to the voltage or potential difference across the fixed resistor. Thus, we can determine the unknown voltage. Another example of ...
