What is a Multimeter?
A multimeter combines several electrical meters into one handheld unit. Basic multimeter models can measure voltage, current and resistance. Advanced models can also measure temperature, inductance, capacitance, duty cycle and frequency. They can also test diodes and transistors. Some even work as an oscilloscope. The two main types of multimeter are digital and analogue.
A multimeter measures electrical properties such as AC or DC voltage, current, and resistance. Rather than have separate meters, a multimeter combines a voltmeter, an ammeter, and an ohmmeter. Electricians and the general public might use a multimeter on batteries, components, switches, power sources, and motors to diagnose electrical malfunctions and narrow down their cause. The two main kinds of a multimeter are analog and digital. A digital multimeter has an LCD screen that gives a straight forward decimal read out, while an analog display moves a bar through a scale of numbers and must be interpreted. Any multimeter will work over a specific range for each measurement. Select one that’s compatible with what you meter most, from low-voltage power sources to high-voltage car batteries. Multimeters are specified with a sensitivity range, so make sure you get the appropriate one. As a voltmeter, a multimeter can measure the amount of AC or DC voltage flowing through a circuit.
