A multimeter, also known as a multimeter, three-in-one meter, or multifunction meter, is a versatile and multi-range measuring instrument. Generally, a multimeter can measure DC current, DC voltage, AC voltage, resistance, and audio levels. Some models can also measure AC current, capacitance, inductance, and certain parameters of semiconductors. It is a commonly used tool for … Read more
Click the “blue text” above to follow us We all know that a multimeter is an essential maintenance tool for electrical workers. Proper use of a multimeter can not only make our work more efficient but also enhance our safety and effectiveness. 1. Before using the multimeter, perform a “mechanical zeroing”; 2. Do not touch … Read more

A multimeter, also known as a multimeter, three-in-one meter, or multifunction meter, is a versatile measuring instrument that can measure direct current (DC) and alternating current (AC) voltage, resistance, and audio levels. Some models can also measure AC current, capacitance, inductance, and certain parameters of semiconductors (such as β). AC Voltage Measurement: As shown in … Read more
1.The multimeter is divided into analog and digital multimeters. As shown in the figure below, the left image is an analog multimeter, and the right image is a digital multimeter. 2.The function of the multimeter is to measure AC voltage, DC voltage, DC current, resistance, and other multifunctional measurements. 3.Pre-use checks for the multimeter. (1) … Read more
The reason a multimeter can measure current, voltage, and resistance lies in its use of a sensitive galvanometer. When a small current passes through the meter, the needle will indicate a value. However, the galvanometer cannot directly handle large currents, so it is necessary to connect some resistors in parallel or series with the galvanometer … Read more
How to use a multimeter? This is a small problem for many new electricians or home users; having a multimeter but not knowing how to use it. Today, we will talk about the functions of the multimeter. The multimeter is an essential measuring instrument for electricians, primarily used for measuring voltage, current, and resistance. Multimeters … Read more
1. Appearance of the Multimeter. A multimeter is an instrument used to measure parameters such as voltage, current, and resistance. There are two types: analog and digital, and its appearance is shown in Figure 1. Figure 1 Multimeter 2. Preparation Before Using the Multimeter. (1) Place it Horizontally. Place the multimeter horizontally. (2) Check the … Read more
This is a supplement to previous content. Earlier, we published an article on measuring breakpoints, and many friends mentioned the use of multimeters. Indeed, we have published relatively little content on the use of multimeters, but they are quite versatile in practical projects. So let’s explore this topic together. 1. What is a Multimeter Also … Read more
