Guide to choice Digital Multimeters
What is an ammeter or multimeter?
This question is one of the most frequent questions that many people interested in the field of electricity and electronics face. Multimeter is one of the most used measuring devices in electrical and electronic laboratories. However, a large percentage of users do not know how to buy this device, they may ask themselves what is the best digital multimeter brand? Or what is the best multimeter for mobile repairs? If you are among this group of people and are thinking of buying the best multimeter, stay with Pars Electronics for the rest of this article.
Type-of-Multimeter: It has been tried to explain some points about choosing a multimeter according to the needs of different users. By reading this multimeter buying guide, you can choose the best digital multimeter model that suits your needs at a reasonable price by knowing enough about this device.
What is a digital multimeter?
The basis of multimeter work is the same, but different types of these devices have been produced and marketed according to different applications, such as testing electrical components or testing electronic circuits. Types of multimeters are divided into two categories, analog or needle multimeters and digital multimeters. Also, this device is produced in two types of desktop and portable multimeters for different applications. In addition, another group of multimeters have been made to measure high amperes, which are known as clamp multimeters.
The new generation of this measuring device is called a digital multimeter. This electronic device is designed to measure electricity quantities such as potential difference or voltage, resistance and current and shows the measured values as numbers on the screen. You can see the best multimeters available in the Iranian market and the features of each by referring to the digital multimeter page.
What is the function of a multimeter?
Getting to know the use of digital multimeter
This device actually performs the work of three ohmmeters, voltmeters and ammeters together in a combined way. In this way, several electrical quantities such as volts, amperes and ohms can be measured with a multimeter. Capacitor testing can be done with a digital multimeter in many cases. Using advanced digital multimeters, the frequency and temperature can also be measured. The use of digital multimeter is very diverse, measuring milliamps, microamps, diode test, connection test, etc. are other uses of digital multimeter. The electrical applications of the multimeter are not limited to testing electronic components, repairing household appliances, and repairing electronic circuits. The multimeter is used wherever there is a need to measure voltage and current.
The instantaneous sampling speed in the multimeter is very low, so they are not able to display the waveform. For this purpose, in some cases, a digital oscilloscope is used to observe the voltage and its momentary changes.
