So what car problems currently can be diagnosed with a digital multimeter? Are you struggling for time and would like a quick overview of our best multimeter picks? Voltage measurements cover the millivolt range and rise well in excess of the 12 volts typical of automotive electrical systems. A good multimeter can measure voltage, current, and resistance. Consequently, instead of having to manually switch through a selection of ranges until you find the right one say, you know you want to measure voltage but don't know quite how big a voltage an auto-ranging multimeter will just display an appropriate readout immediately. Feature-wise, the Ultrics digital multimeter sports a relatively large, blue back-lit LCD display that provides clear readouts. Generally speaking, the currents involved in car electrical systems are much lower than in the home, although it's worth checking the specific ratings to ensure each unit is capable of measuring what you need.
