What is a multimeter
A test tool that can be used to measure two or more electrical values is known as a multimeter. Usually a digital multimeter measures current, voltage and resistance. In the field of electronics and electrical, this tool is commonly used by technicians. A long time ago, the usage of analog multimeters was more profound. It was replaced by the digital multimeter due to greater accuracy, reliability and improved impedance(The New Best Cheap Multimeter Reviews by whichsolderingstation). The multimeter combines the functionalities of single meters such as an ammeter, voltmeter and ohmmeter. Some multimeters also include other special functions. According to our need, different types can be purchased. In this post, we will give an executive review of 5 top-rated budget multimeters. Click the links to read the multimeter reviews for several affordable models in details.
The functionalities of a multimeter include measurement of AC/DC voltage and AC/DC current. The current is nothing but the rate of flow of charge while voltage is the potential difference in charge between two points in an electric field. It can also measure resistance and continuity. The SI unit of electrical resistance is known as Ohm and it is defined as the transmission of the current of one ampere when there is a potential difference of 1 volt.
Multimeters also have the functionality of measuring diodes. They can do it in 2 ways: Ohmmeter mode or Diode mode. In case an error is shown in the values, the diode is said to be defective. The defect of the diode can be either open or short. Open diode implies the fact that current will not flow through it during forward or reverse biased condition while shorted diode means it is conducting. In addition to the above functions, a multimeter can also measure the capacitance of capacitors.
Additional features of a multimeter include the measurement of temperature, display backlight, Auto-ranging, Maximum value hold and Auto power off. Temperature measurement is useful because while working with a microprocessor or other similar parts, we can find out whether it overheats or not. Overheating can lead to serious fluctuations in the working of devices such as the microprocessor. The auto-ranging feature allows the multimeter to automatically select the required range of quantity. This will help us to view the significant digits only. The max hold button will allow the user to capture the highest reading. During the in-rush of current flow when the device is first turned on, this feature is particularly useful. For better visibility, LCD backlight display is highly important. The Auto power off feature ensures that the battery of your DMM will last longer thus avoiding unnecessary power loss when you forget to turn it off.
