A multimeter is the preferred tool for electricians to troubleshoot faults. For many electricians, short circuit faults are easy to check with a multimeter, but finding breakpoints is not as straightforward. Today, I will share a method for using a multimeter to check for wire breakpoints. The steps are as follows:1. Connect one end of … Read more
1. Correct Use of the Multimeter To use the multimeter correctly, familiarize yourself with the dial. Adjust the two zero position regulators gently. Choose the correct terminals, ensuring the red and black probes are inserted into the right holes. Turn the switch to the correct range. Select the appropriate measurement range for accurate readings. Ensure … Read more
1. Targeted Measurement with Multimeters 1. Correct Use of Multimeters To correctly use a multimeter, one must be familiar with the dial. Adjust the two zero position regulators gently. Choose the correct terminals, ensuring the red and black probes are inserted into the right holes. Rotate the switch to the correct range setting. Choose the … 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

Some models can also measure AC current, capacitance, inductance, and certain parameters of semiconductors. It is a commonly used tool for electricians. 1. Check the range before … Read more
How to measure leakage current with a multimeter, methods for measuring leakage current with a multimeter. Using the continuity setting of the multimeter, measure between the ground and the circuit being tested. If the meter shows a resistance value, it indicates that there is no insulation. However, in practice, to measure leakage current, a megohmmeter … 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
Article Overview There are three view modes for observing waveforms on an oscilloscope: YT mode, rolling mode, and XY mode. While YT mode is sufficient in most cases, how should rolling mode and XY mode be used? What are the advantages and disadvantages of each mode? Oscilloscopes can observe waveforms through various view modes, including … Read more
The oscilloscope is the most common instrument for electronic engineers, and many people liken it to the “eyes” of an engineer, which sufficiently illustrates how important oscilloscopes are to engineers. How is the signal displayed on the oscilloscope screen? On the oscilloscope, the signal transmission goes through a series of resistors and capacitors inside the … Read more
As one of the most commonly used measuring instruments in the electronics industry, oscilloscopes involve a lot of image import/export, data processing, automation operations, and more. Here, we plan to explain in detail the remote control of oscilloscopes, with the following arrangements: 1 Remote image access and control via wireless network (suitable for special occasions … Read more
