In this article, we will describe the basic measurements of an impedance analyzer. Overview An impedance tester is an instrument used to measure AC resistance or impedance. This article will introduce the basic knowledge about impedance, the measurement method of impedance, and how to use the impedance tester. What is impedance? What is impedance? In short, it is "a quantity that indicates the difficulty of the flow of alternating current". ...
The article will cover the basics of impedance and points of measurement. Impedance is the resistance of an AC circuit and is invisible. Therefore, it must be measured using a specialized measuring instrument such as an impedance tester. People who have never touched an impedance tester before may be more concerned about how to use it and what to look for when using it. Therefore, this article will present in an easy-to-understand way the...
Want to know how to use the current probe? Please first understand the following basic usage of the current probe and precautions for use. Since electricity is invisible, it is not possible to immediately determine whether a malfunction has occurred. In some cases, current measurements are required on a daily basis to prevent malfunctions, as well as to identify the cause of malfunctions when they do occur. Digital multimeters, clamp meters, and current probes can be used...
Many people use digital multimeters to easily measure current, voltage, resistance, etc. However, there is a drawback to using a digital multimeter to measure current, namely: the circuit must be disconnected and the digital multimeter must be connected in series with the circuit under test in order to make the measurement. In this case, a current probe can be used instead of a digital multimeter to make measurements. Since the electrical connection of the circuit is no longer required, the current probe is more time-consuming...
Digital multimeters are used, and this article will detail their advantages and disadvantages. ■ SUMMARY Electronic devices are powered by electricity. However, because electricity is invisible, it is necessary to use measuring instruments such as digital multimeters to check their safety and quality and to find out why malfunctions occur. Digital multimeters have so many buttons and ports that many people find them difficult to manipulate at first...
This article describes its basic information and how it differs from an analog multimeter. ■ Summary The condition of an electronic device needs to be determined using a measuring instrument. For electronic devices whose condition cannot be determined visually, it is recommended that measurements be made with a digital multimeter. In this section, basic information about digital multimeters such as "What is a digital multimeter" and "Is there a difference between a digital multimeter and an analog multimeter" will be explained in detail...
If you want to measure current, voltage, etc., you need specialized measuring equipment. Analog and digital multimeters are usually used to measure current, but the circuit must be cut off and the multimeter and the circuit connected in series in order to make the measurement. However, it is not uncommon that it is not possible to disconnect the circuit in some cases. In addition, there is a danger of electric shock when the circuit is disconnected. In this case the clamp meter...
This article will detail the basics of a clamp meter and the principles of measurement. When it comes to instruments that measure current, many people may think of analog or digital multimeters. However, if you want to make measurements without breaking the circuit, a clamp meter is recommended. Direct wiring method ...
How to measure frequency? Measurable Devices, Measurement Methods, and Precautions In everyday life, many people say they don't know much about the frequencies of electrical appliances. However, some electrical appliances have specific compatible frequencies, and using electricity at a frequency that is not compatible with the product may lead to malfunctions, fires, and other risks. In addition, in industrial equipment, there are electrical designed to operate at fixed or variable frequencies...
What does the frequency of electricity mean? Here are the basics of frequency, regionality, and measurement Since electricity and voltage are invisible things, many people will think they are elusive. But in fact, they are only invisible, and it is not difficult to understand them. Below, we will introduce the frequency basis of electricity and voltage in an easy-to-understand way, regional differences in frequency, and how...
